| Abstract: Meine Emeritierung 2016 ist der Anlass zu diesem Rückblick und Vorblick auf 40 Jahre Geoinformation. Die Entwicklung werde ich in fünf Dekaden gruppieren und mich auf die dominante Praxis und weniger auf genaue Daten für die Ankündigungen von neuer Technologie beziehen. Am Schluss werde ich eine Projektion für die 2020er Dekade wagen - auch wenn Voraussagen immer gefährlich sind, besonders wenn sie die Zukunft betreffen. Ich hatte das Glück praktisch alle führenden Geoinformations-Wissenschaftler und - Unternehmer noch persönlich kennengelernt zu haben. Ich berichte bewusst weder vollständig noch objektiv; der Fokus liegt auf Anwendungen, die von vielen genutzt werden. Dennoch glaube ich schließlich zu einigen bedenkenswerten Schlüssen zu kommen.br>Die Entwicklung von GIS ist durch enabling technologies getrieben; deshalb werde ich für jede Dekade zuerst die jeweils neuen, allgemein gebräuchlichen Informations- aber auch Vermessungstechnologien charakterisieren, um dann die Geoinformationspraxis und die Geoinformationsforschung beschreiben und danach Veränderungen bei den verfügbaren Daten und Software anzumerken. Die Preisreduktion für Informationstechnologie war und ist wohl der wichtigste Antrieb der Entwicklung der letzten Jahre. In Abbildung 1 zeichne ich die ungefähr einem erweiterten Moore'schen Gesetz folgende Entwicklung des Preises eines GIS Arbeitsplatzes auf; die Entwicklung von IT hat die Kosten der Bestimmung einer Position auf der Erdoberfläche durch GPS drastisch reduziert (schätzungsweise von $1000 auf $.01 pro Punkt) und die Anzahl der Rechner, mit denen Daten ausgetauscht werden könnten, hat durch das Internet in noch höherem Masse zugenommen, was in Abbildung 1 ebenfalls dargestellt ist. |

| Abstract: A natural language interface will improve the human-computer interaction with Geographic Information Systems (GIS). A prerequisite for this is the mapping of natural language expressions onto spatial queries. Previous mapping approaches using, for example, fuzzy sets, failed because of the flexible and context-dependent use of spatial terms. Context changes the interpretation drastically. For example, the spatial relation ''near'' can be mapped onto distances ranging anywhere from kilometers to centimeters. We present a context-enriched semiotic triangle that allows us to distinguish between multiple interpretations. As formalization we introduce the notation of contextualized concepts that is tied to one context. One concept inherits multiple contextualized concepts such that multiple interpretations can be distinguished. The interpretation for one contextualized concept corresponds to the intention of the spatial term, and is used as input for a spatial query. To demonstrate our computational model, a next generation GIS is envisioned that maps the spatial relation ''near'' to spatial queries differently according to the influencing context. |

| Abstract: Different forms of spatial descriptions are used to communicate information in the context of navigation in urban environments. When generated by computers, such descriptions are combinations of map features in a predefined way. Unlike computers, however, people are capable of flexibly generating navigational spatial descriptions by taking into account a wide array of different contextual factors, e.g. a user's prior knowledge and the structure of the environment. This paper deploys the notion of pragmatics to compare formal addresses, route descriptions (generated either by computers or humans), and destination descriptions in terms of their adaptability to contextual factors in order to identify the means to creating more cognitively sound information systems. |

| Abstract: The characterization of place and its representation in current Geographic Information System (GIS) has become a promoinent research topic. The paper concentrates on places that are cognitive regions, and presents a computational framework to deriuve the geographic footprint of these regions. The main idea is to use Natural Language Processing (NLP) tools to identify unique geographic features from User Generated Content (UGC) sources consiting of textual descriptions of places. These features are used to detect on a map an initial area that the descriptions refer to. A semantic representation of this area is extracted from a GIS and passed over to a Machine Learning (ML) algorithm that locates other areas according to semantic similarity. As a case study, we employ the proposed framework to derive the geographic footprint on the historic center of Vienna and validate the results by comparing the derived region against a map of the city. |

| Abstract: Recent years have witnessed a growing production of Volunteer Geographic Information (VGI). This led to the general availability of semantically rich datasets, allowing for novel ways to understand, analyze or generalize urban areas. This paper presents an approach that exploits this semantic richness to extract urban settings, i.e., conceptually-uniform geographic areas with respect to certain activities. We argue that urban settings are a more accurate way of generalizing cities, since it more closely models human sense-making of urban spaces. To this end, we formalized and implemented a semantic region growing algorithm-a modification of a standard image segmentation procedure. To evaluate our approach, shopping areas of two European capital cities (Vienna and London) were extracted from an OpenStreetMap dataset. Finally, we explored the use of our approach to search for urban settings (e.g., shopping areas) in one city, that are similar to a setting in another. |

| Abstract: Comparative literature investigates texts simultaneously in multiple languages. It is by definition conducting corpus-based research (each study is based on a quantitatively discernible number of texts chosen by single sets of qualities), in practice however it is facing diverse limitations which restrict the value of generalized statements. We propose to extend well approved methods of corpus-based research to computational comparative literature in order to overcome those limitations. The core is the construction of a large corpus of annotated literary texts with a related set of computational analysis methods. The aspects of the proposed technical solution make it even suited for the comparison of multi-lingual text corpora, as the same methods can be applied to all texts irrespective of language. Computational comparative literature has a supportive function for established approaches in comparative literature. It allows for systematic evaluation of a large number of texts that goes beyond established questions. |

| Abstract: A corpus of text to be used for literary analysis, but generaly for other corpora in many other document oriented fields of digital humanities, must provide methodsbr>- to add and remove texts from the corpus,br>- to inquire about the texts in the corpus andbr>- to query the content of the corpus.br>RDF to structure document storage and SPARQL as a flexible query language are suitable to build, maintain and use corpora.br>We report on a system to prepare text for inclusion in a corpus for literary analysis, where text structure is annotated partially automatic and the result of linguistic analysis included in the same corpus. Analysis of the text can use SPARQL to extract text parts or produce statistics.Three experiments have shown us that requirements for (i) literary analysis of a single authors work, (ii) the analysis of specific aspects of a limited set of texts - the ontology of fairy tales - or (iii) a wide ranged, mostly statistical, analysis of a large number of texts pose the same fundamental requirements. |

| Abstract: Data is spatial if it contains references to space. We can easily detect explicit references, for example coordinates, but we cannot detect whether data implicitly contains references to space, and whether it has properties of spatial data, if additional semantic information is missing. In this paper, we propose a graph model that meets typical properties of spatial data. we can, by the comparison of a graph representation of a ata set to the graph model, decide whether the data set (implicitly or explicitly) has these typical properties of spatial data. |

| Abstract: Geographic data is expensive to collect and maintain and sharing data is crucial for its effective use in urban planning at all levels. For a few hardly ever changing themes the simple distribution of copies of data is feasible, but for other data, access to ''live'' data and updating, sometimes even distributed updating, of the data is necessary.br>The organization of sharing data can be separated into three sets of issues: (1) Interpretation: how to understand the data, (2) Authorization: is a user permitted to use the data, and (3) Access: how to achieve effective and non-disturbing use and updating of data by several users? Solutions must take threats into account: hackers may try to steal or disturb the use of data, and the revelations of Snowden's documents only emphasize the danger of others reading data not intended for their eyes.br>Effective sharing geographic data without conflicts requires integrating results from different areas of computer science research, including at least: cryptography, computer security, database management, and computer networking. |

| Abstract: Whenever a person gets lost and there is no way to access stored spatial information, e.g. in the form of maps, she needs to rely on the knowledge of other humans instead. This situation can be modelled as a communication setting where a person lacking spatial knowledge requests information from a knowledgeable source. The result are cognitive transactions in which information over various levels of detail (LoD) is negotiated. The overall goal is to agree on a shared spatial representation with equal semantics, i.e., a common ground. We present a communication model that accounts for establishing a common ground between two agents. The agents use a modified ''wayfinding choreme'' language and special signals to negotiate the LoD. Findings of a case study were used to verify and refine our work. |

| Abstract: Many services need to understand what a user means with a word. For example, on-demand map services must predict which content is requested. We show a computational model in which map content is selected using sentences which are uttered in the context of the map request and which stand for the context of the request. br> The model is based on a proposal by Aerts et al. to apply a quantum-mechanical framework to model human concepts and their interactions. It is well known that human use of contexts and their interaction demonstrates effects which cannot be modeled with simple logic and probability.br> The paper shows how this model is applied to a small problem: generating a map for a boat trip on the canals of southern France, where friends traveling by car will join us for an evening. Different parts of the task-describing sentence are taken as context, and are applied to restrict the desired map content. The result is used to select a Web Feature Server and the desired features. br>The paper shows the applicability of the formalism and ends with suggestions for further work on achieving practical solutions. |

| Abstract: Human use of categories exhibits a prototype effect; concepts become more defined through a conversation. Modelling these gradual clarification of what a word signifies is equally important in human - computer interactions, for example in interactions about geographic concepts and the information that is needed in a given situation. We address here the simplified, but essentially realistic, question of what is meant by ``map'' and how the concept is refined. We apply the methods Aerts, Gabora and Rosch have described and explore how they can be integrated into practical systems. br> In this paper we explore the optimal selection of a map through a conversation with the client to elucidate their intentions. The example case contains effects which are similar to the ``guppy effect'' that is known from literature and is a key reason to apply quantum mechanic formalism. The results are promising, and we sketch the extension to the construction of ``custom made'' maps from layers. This will provide users with maps that optimally reflect what map elements should be visible for use in a given context. |

| Abstract: The location check-in data, developing along with social network, are considered as user-generated crowd-sourcing geospatial data. With massive data volume, abundance in contained information, and high up-to-date status, the check-in data provide a new data source for geographic information service represented by location-based service. However, there is a significant quality issue regarding to crowd-sourcing data, which has a direct influence to data availability. In this paper, a data quality analysis approach is designed for the location check-in data and a check-in data uncertainty model is proposed. First of all, the quality issue of location check-in data is discussed. Then, according to the characteristics of check-in data, a location check-in data quality analysis and data processing approach is proposed, using certain standard dataset as reference to conduct an affine transformation for the check-in dataset, during which the RANSAC algorithm is adopted for outlier elimination. Subsequently, combining GIS data uncertainty theory, an uncertainty model of processed check-in data is set up. At last, using location check-in data obtained from jiepang.com as experimental data and selected navigation data as data standard, multiple location check-in data quality analysis and uncertainty modeling experiments are conducted. By comprehensive analysis of experimental results, the feasibility of proposed location checkin data quality analysis and process approach and the availability of proposed uncertainty model are verified. The novel approach is proved to have a certain practical significance to the study of the quality issue of crowd-sourcing geographic data. |

| Abstract: Navigation-tools currently give us directions from location A to B. They help us with the physical process of moving from here to there. Tasks in general, are achieved by the subsequent determination and execution of sub-tasks until the goal is achieved. To help achieve the higher-ranking task, we commonly use so called ''personal information management''-tools (PIM-tools). They offer possibilities to manage and organize information about errands that have personal or social implications. Such tasks are described in informal ways, todo-lists for example offer the storage of textual description of an errand, sometimes allowing geographic or temporal information to be added. The paper proposes a formalism that can produce instructions leading from A to the fulfilment of the ''task''. Thus connecting the high-level task, that represents intentions, with the physical level of navigation. |

| Abstract: 3D city models are getting more important as a field of research and business and received an increasing amount of attention from both the scientific community and the professional field. 3D city models are one of the new tools for sustainable city development. Since development questions occur repeatedly, the used city models should be maintainable, i.e. the system should be kept up-to-date and not be created new for each decision. This is a challenge. Creating a model representing the current status of a city has been addressed in research literature. The major challenge is the vast amount of data to be collected, processed and visualised. However, keeping the resulting model up-to-date has not been discussed yet. Updating requires the introduction of a suitable concept of time in the model. This would then allow representing historic and current status of the city as well as future scenarios. Processes provide the connection between different points in time. Processes also change the appearance of the city and need to be represented in the model for change detection. In this paper, we discuss the challenges and show necessary properties for city models and systems maintaining them to reach a reasonable level of maintainability. |

| Abstract: Space and time are the most prominent features of our everyday experience. While we can movebr>relatively freely within and interact with space, time imposes stricter restrictions on us. We arebr>mere bystanders to the ever-changing flow of time. Close observation of our environment revealsbr>that nothing stands still and everything changes constantly.br>It is generally acknowledged that GIS need to account for the dynamic aspects of the world.br>The almost exclusive depiction of static phenomena (spatial configurations) in GIS reveals itsbr>close historical ties to Cartography. A first call to move beyond the ''map metaphor'' and focusbr>on ''spatial processes, changing the spatial configuration'' can be found in Abler et al. (1971). Anbr>integration of processes in GIS will help to answer questions related to ''When somethingbr>happened or will happen'' (Frank 1998). For a thorough review focusing on the dynamic aspectsbr>in GIS research see Worboys (2005). The vision of a fully dynamic GIS requires a simple,br>combinable, and scalable formal application-independent approach (Weiser and Frank 2010).br>In this work we present our ongoing research on (1) how to represent processes over multiplebr>levels of detail, (2) their combination, and as a result (3) reasoning over processes. We buildbr>upon the notion of ''processes over multiple levels of detail (LoD)'' we have formalizedbr>previously, using partial function application (Weiser and Frank 2012). We now focus on thebr>challenges that arise from combining those processes. |

| Abstract: Personal Information Management is the study of how people store andbr>retrieve data for their purposes. Traditionally the data is stored in applications like calendars, todo-lists, address books, etc... These applications or PIM-tools do not take the spatial character of much of the information into account. But space, just as time plays a major role in the way we organize and utilize personal information.br>In this paper we present ongoing research in which we try to identify a proper formalism for integrating space into PIM-tools. We therefore attempt to model an ordinary task from daily life experience and expect to find answers to the question of how and what to integrate into a system to move from a regular PIM-tool to a spatial-PIM. |

| Abstract: Traditionally personal information management (PIMs) tools supportbr>people in their daily tasks. While research around personal information management focuses on how to store and retrieve information e ciently,we focus on the use of spatial (geographic) aspects in personal information. Tasks and appointments are represented in calendars or todolists,br>often including temporal and sometimes even spatial information. Un-br>fortunately the spatial information is seldom used for task planning or execution support. Therefore current PIM applications, e.g. on mobile phones, do not use the full power of the devices, and they too often simply resemble a piece of paper with the relevant information on it. The research goal is to extend the possibilities of modern GIS and enable ubiquitous GPS technology to pro-actively support the user in his daily tasks. |

| Karimipour F (2010), "A Mathematical Tool to Extend 2D Spatial Operations to Higher Dimensions". Thesis at: University of Tehran. |
| Abstract: 3D and temporal objects must be included in GIS to handle real world phenomena. Many have studied extension of spatial operations to these multi-dimensional spaces and suggested technical solutions to extend a spatial operation to a new multi-dimensional space. These technical approaches have led to developments which can not be generalized. One technique used to extend a spatial operation from 2D to a multi-dimensional space is not likely usable for another spatial operation, nor to extend the same spatial operation to another multi-dimensional space. This paper suggested studying spatial operations via their dimension-independent properties. It intends to construct a mathematical framework to integrate spatial operations of different multi- dimensional spaces (3D and time) a GIS should support. The framework will be independent of the space in which the operations are applied using algebraic structures - and more specifically category theory - that ignore those properties of operations which depend on the objects they are applied to. Implementations for some case studies for spatial operations of moving points are presented. |

| Abstract: Intersection computation is one of the fundamental operations of computational geometry. This paper presents an algorithm for intersection computation between two polygons (convex/nonconvex, with nonintersect- ing edges, and with or without holes). The approach is based on the de- composed representation of polygons, alternate hierarchical decomposition (AHD), that decomposes the nonconvex polygon into its convex compo- nents (convex hulls) arranged hierarchically in a tree data structure called convex hull tree (CHT). The overall approach involves three operations (1) intersection between two convex objects (2) intersection between a convex and a CHT (nonconvex object) and, (3) intersection between two CHTs (two nonconvex objects). This gives for (1) the basic operation of intersec- tion computation between two convex hulls, for (2) the CHT traversal with basic operation in (1) and, for (3) the CHT traversal with operation in (2). Only the basic operation of intersection of two convex hulls is geometric (for which well known algorithms exist) and the other operations are re- peated application of this by traversing tree structures. |

| Abstract: In the last decade 3D city models received an increasing amount of attention from both, the scientific community and the professional field. One of the requirements for city models is that they should be maintainable, i.e., the system should be kept going and not be created for a specific decision and then abolished. What is the effect of such a requirement? Creating a model that represents the current status of a city is only problematic due to the vast amount of data to be collected and processed. Keeping the resulting model up-to-date, however, is more complex. This requires, for example, the introduction of ‘time’ as a concept in the model because then it can comprise the history and current status of the city as well as future development scenarios. The processes that lead to changes in the city must thus be represented in the city model to allow the changes. In the paper we discuss these problems and show necessary properties for city models and systems maintaining them to reach a reasonable level of maintainability. |

| Andrew U (2010), "Reviewing Geoinformation in the Light of Recent Economic Theory" |
| Abstract: Understanding the value of GIS is understanding the value of the information produced by the GIS; early GIS proponents argued for the economic advantages of geographic information systems using standard methods of management science. Only after ad- vances in economic theory during the 20th century were absorbed by GI scientists, a theory to establish the value of geographic information per se could be approached. In this essay, I trace the development by discussing contributions assignable to six Nobel Laureates in economy. After a brief outline of how value of geographic information can be measured, challenges posed by the contributions of two recent Nobel Laureates to GIS and its use are discussed. |

| Abstract: This paper studies emergence/generation of power law in rank-order distribution of axial line length, which is a global pattern observed in real cities, due to interaction of a set of seven simple spatial rules at a local scale. These rules and their interactions form a model expected to simulate the morphological structure of free spaces in unplanned organic pedestrian small cities. Effects of each of the seven rules are discussed through repeated simulations of eight possible combinations of the rules, using a bottom- up process. The results show that the rules generate environments with statistically stable rank-order distribution of axial line length that follows the power law. It means that the axial maps of the simulated environments have a scale-free hierarchical structure such that their distributions lean toward short axial lines. It also represents dominance of local spatial structure, as the model renders a faster rate of growth at a local scale while allowing a steady growth at a global scale. |

| Abstract: Object representation and reasoning in vector based geographic information systems (GIS) is based on Euclidean geometry. Euclidean geometry is built upon Euclid’s first postulate, stating that two points uniquely determine a line. This postulate makes geometric constructions unambiguous and thereby provides the foundation for consistent geometric reasoning. It holds for exact coordinate points and lines, but is violated, if points and lines are allowed to have extension. As an example for a point that has extension consider a point feature that represents the city of Vienna in a small scale GIS map representation. Geometric constructions with such a point feature easily produce inconsistencies in the data. The present paper addresses the issue of consistency by formalizing Euclid’s first postulate for geometric primitives that have extension. We identify a list of six consequences from introducing extension: These are ‘new qualities’ that are not present in exact geometric reasoning, but must be taken into account when formalizing Euclid’s first postulate for extended primitives. One important consequence is the positional tolerance of the incidence relation (“on”-relation). As another consequence, equality of geometric primitives becomes a matter of degree. To account for this fact, we propose a formalization of Euclid’s first postulate in Łukasiewicz t-norm fuzzy logic. A model of the proposed formalization is given in the projective plane with elliptic metric. This is not a restriction, since the elliptic metric is locally Euclidean. We introduce graduated geometric reasoning with Rational Pavelka Logic as a means of approximating and propagating positional tolerance through the steps of a geometric construction process. Since the axioms (postulates) of geometry built upon one another, the proposed formalization of Euclid’s first postulate provides one building block of a geometric calculus that accounts for positional tolerance in a consistent way. The novel contribution of the paper is to define geometric reasoning with extended primitives as a calculus that propagates positional tolerance. Also new is the axiomatic approach to positional uncertainty and the associated consistency issue. |

| Abstract: A central task of a multidisciplinary projects is to explain and declare the concepts and connections of concepts of all the different disciplines and participants involved. Ontologies and their tools can clarify and interpret the differences between words in context of multidisciplinary users even though in a customary familiar context such words appear to have the same meaning. Ontologies are formal descriptions of concepts that are useful to achieve sharing of computerized files. Ontologies describe things and operations that can be applied to them. They improve communication between people, especially if they communicate indirectly by sharing computerized databases, through organized concepts used to encode the perception of reality in computer representations. The configuration of the central database in which results of disciplines are allocated in a reusable way follows from the formal ontology. The presented tiered ontology distinguishes between simple observations, physical objects that the observer conceptualizes, and the socially constructed objects of social reality. Operations connect between different concepts in a traceable way. A tiered ontology contributes to the separation of observation of physical facts from their interpretation; they are thus important in multi-disciplinary and multi-language research teams. A formal ontology translates to a tool to help the archaeologist to record his observations in a form later reusable and integrable with the results from others! |

| Frank AU (2010), "Why Context Matters in Giving Driving Instructions ---The Necessity for Representing Decision Points" |
| Abstract: A critical review of past research can lead to identify new, fruitful research directions: here I consider the research on driving instruction by linguists and, especially, by Geoinformation scientists, which has concentrated on static spatial situations. The insight obtained from qualitative spatial reasoning is limited because it did not include actions, change, and motion. The important use case for dynamic spatial behavior is navigation: how are instructions communicated to an actor, e.g., from the car navigation system to the driver and how are they acted upon? An analysis of the communication situation must be dynamic; while moving the driver identi es decision situations at points where instructions are expected. The participants in way nding communication must have the decision situations as shared context. Maps represent static spatial situations (Kuhn, 2010) and miss the dynamic situations a navigator encounters. Research on recognition of decision situations is recommended to identify decision situatins for the navigation system, which are the context which the navigator assumes to be shared. |

| Abstract: Early Geospatial Information Systems (GIS) dealt with static objects. There is much demand, however, to include temporal objects in these systems. Many have studied this problem and suggested technical solutions for different spatial operations. A common shortcoming is that the extension techniques are highly dependent on the specific case studies and cannot be generalized. In this paper, we propose studying spatial operations via their dimension-independent properties. This research intends to construct a mathematical framework that contains primitives for different operations. The framework will be independent of the space in which the operations are applied using algebraic structures-and more specifically category theory-that ignore those properties of operations which depend on the objects they are applied to. Implementations for some case studies are presented. |

| Abstract: The effort to clarify the terminology to describe wayfinding was overdue and I applaud Wiener, Büchner, and Hölscher for their contribution [ref to previous article]. A clear terminology is important for reporting and discussing wayfinding research, but it is probably important for the design, planning, and analyzing of experiments as well, which suggest a Whorfian like hypothesis in science! I have three comments regarding their taxonomy: 1. They advertise a taxonomy, but their important contribution is in the identification of properties they use to distinguish the taxa. 2. Their definitions may lead to misunderstandings; replacing the verbal descriptions by formal definitions using a computational model avoids ambiguities. 3. They classify the wayfinding task based on the knowledge of the navigator alone; the environment should be included to achieve a more precise comprehensive, with all factors influencing the selection of a strategy. |

| Frank AU (2009), "Multi-cultural Aspects of Spatial Knowledge", In GeoSpatial Semantics. Heidelberg , pp. 1-8. Springer. |
| Abstract: It is trivial to observe differences between cultures: people use different languages, have different modes of building houses and organize their cities differently, to men- tion only a few. Differences in the culture of different people were and still are one of the main reasons for travel to foreign countries. The question whether cultural differ- ences are relevant for the construction of Geographic Information Systems is longstanding (Burrough et al. 1995) and is of increasing interest since geographic information is widely accessible using the web and users volunteer information to be included in the system (Goodchild 2007). The review of how the question of cultural differences was posed at different times reveals a great deal about the conceptualiza- tion of GIS at different times and makes a critical review interesting. At the heart of the discussion of cultural differences relevant for GIScience is a Whorfian hypothesis that different cultural backgrounds could be responsible for dif- ferences in the way space and spatial relations are conceived. Whorf claimed that people using a language with more differentiation, for example in terms describing different types of snow, also perceive reality differently from people using a language with less differentiation (Carroll 1956). An early contribution picked up on sugges- tions made by Mark and others (Mark et al. 1989b) and identified several distinct is- sues that could be investigated individually (Campari et al. 1993): 1. the cultural assumptions that is built into the GIS software may differ from those of the user; 2. the influence of decision context in which a GIS is used; 3. the conceptualization of space and time may differ; 4. differences in the administrative processes and how they structure space; 5. the sense of territoriality, ownership or dominance of space, is different between people, again citing ethnographic examples; 6. the influence of the material culture, the ecosystem, economy and technology. Campari and Frank in this early paper asked the question whether a single or a few GIS software packages could serve universally or local (national) development of GIS software, which still existed at that time, were justified by cultural differences. |

| Frank AU (2009), "Scale Is Introduced in Spatial Datasets by Observation Processes", In Spatial Data Quality From Process to Decision. , pp. 17-29. CRC Press. |
| Abstract: An ontological investigation of data quality reveals that the quality of the data must be the result of the observation processes and the imperfections of these. Real observation processes are always imperfect. The imperfections are caused by (1) random perturbations, and (2) the physical size of the sensor. Random effects are well-known and typically included in data quality descriptions. The effects of the physical size of the sensor limit the detail observable and introduce a scale to the observations. The traditional description of maps by scale took such scale effects into account, and must be carried forward to the data quality description of modern digital geographic data. If a sensor system is well-balanced, the random perturbations, size of the sensor and optical blur (if present) are of the same order of magnitude and a summary of data quality as a `scale' of a digital data set is therefore theoretically justifiable. |

| Abstract: Observations and processing of data create data and their quality. Quantita- tive descriptors of data quality must be justified by the properties of the observation process. In this contribution two unavoidable sources of im- perfections in the observation of physical properties are identified and their influences on data collections analyzed. These are, firstly, the random noise disturbing precise measurements; secondly, finiteness of observa- tions—only a finite number of observations is possible and each of it aver- ages properties over an extended area. These two unavoidable imperfections of the data collection process de- termine data quality. Rational data quality measures must be derived from them: Precision is the effect of noise in the measurement. The finiteness of observations leads to a novel formalized and quantifiable approach to level of detail. The customary description of a geographic data set by ‘scale’ seems to relate these two sources of imperfection in a single characteristic; the the- ory described here justifies this approach for static representation of geo- graphic space and shows how to extend it for spatio-temporal data. |

| Abstract: 3D and temporal objects must be included in GIS to handle realbr>world phenomena. Many have studied extension of spatial operations to these multi-dimensional spaces and suggested technical solutions to extend a spatial operation to a new multi-dimensional space. These technical approaches have led to developments which can not be generalized. One technique used to extend a spatial operation from 2D to a multi-dimensional space is not likely usable for another spatial operation, nor to extend the same spatial operation to another multi-dimensional space. This paper suggested studying spatial operations via their dimension-independent properties. It intends to construct a mathematical framework to integrate spatial operations of different multidimensional spaces (3D and time) a GIS should support. The framework will be independent of the space in which the operations are applied using algebraic structures - and more specifically category theory - that ignore those properties of operations which depend on the objects they are applied to. Implementations for some case studies for spatial operations of moving points are presented. |

| Abstract: Due to popular use of internet and fast progress of communications technology, the researches related to GIS in environmental models is being focused to use Geospatial Information System (GIS) in a Service Oriented Architecture (SOA). In this architecture, the geo service requesters can access the provided geo-services through the communication network by using client/server method. Effectiveness of the method depends on the existence of interoperability especially at semantic level. Lack of semantic interoperability makes obstacles for automated discovery of geo-services. The current article proposes a methodology based on ontology for discovering field-based geo-services. An ontological structure including the ontology of measurement theory, the core ontology of geo services and the upper ontology supports semantic framework for this methodology. In the other words, these ontologies provide required knowledge for describing ontologies of provided and requested geo-services. Sample ontologies have been built to test the implementation of the proposed methodology for discovering geo-services. In this regard, a geo-service discovery application has been developed by this research in order to implement a prototype of the methodology. |

| Abstract: Service oriented architecture in a distributed computing environment, with loosely coupled geo-services is a new approach for using GIS services in environmental modeling. The messages exchanged must follow a set of standard protocols which support syntactic interoperability, but do not address application semantics. par This article proposes a layer-based ontology with additional layers for describing geo-services, especially the measurement units used. The paper gives an ontology of measurements for describing the input and output of field-based geo-services and a core ontology of geo-services containing the domain concepts. An upper ontology adds new general concepts to an existing ontology in order to achieve an agreement between geo-service developers and environmental modelers. The layer-based structure is the building block for discovering geo-services that support semantic interoperability in GIS and environmental modeling. |

The Association for Computing Machinery, Inc.. |
| Abstract: It has been pointed out repeatedly that spatial operations must bepar extended to include support for 3D and moving objects. The attempt to code by hand each spatial operation for each data type (e.g., static 2D, moving 2D, static 3D, and moving 3D) is forbidding and has led to specific solutions for particular purposes. In this paper, we have advocated an operationindependentpar approach to extend 2D spatial operations to 3D and moving objects. The approach is based on implementation of the concepts of n-dimensional geometry through definition of transformations between domains called ''lifting''.

| Abstract: GIS professionals seem to assume that better data lead to better decisions, but how does one decide when better data lead to a better decision? An analysis to determine the effects of data quality on the quality of decisions provides criteria whether to invest in data quality improvement. This article analyzes data quality and how it influences the quality of a decision. It uses an example of an environmental engineering decision to demonstrate a general method to assess the influence of data quality on the decision. It shows that the uncertainty in aspects, which are poorly known, e.g., the necessary security levels, dominate the uncertainty of many decisions. Efforts to collect more or better data to improve the data quality of those stored in a GIS would not reduce uncertainty in the decision significantly. This result seems to be consistent with results from other studies for this very large class of decisions. The article gives a general method to assess whether collecting better data improves a decision or not. |

| Abstract: Progress in research on data quality is slow and relevance of results for practice is low. Can an ontological analysis make significant contributions? The ''road block'' in data quality research seems to be an ontological one. Approaching ''data quality'' with an ordinary language philosophy method reveals the inherent contradiction in the concept. The ontological analysis reveals the necessity to separate the ontology (reality) proper from the epistemology (data). par Data quality reveals itself when data is used, which focuses our attention on the double linkage between reality and data: (1) the observation that reflects reality into the data and (2) the decision that links the plan to the changes in reality.par The analysis of the processes leading from raw observations to decisions leads to operational definitions for ''fitness for use'' and an effective method to assess the fitness of data for a decision. Novel is the consideration of data quality as transformation through the whole process from data collection to decision. |

| Abstract: In this paper we investigate the necessary interaction between expropriation and the cadastre. We investigate first the role of expropriation in modern society and the stake holders and then analyze the interaction with land registration and cadastre. The ''simple cadastre'' framework allows a treatment independent of national particulars. A simple cadastre is a minimal model that satisfies the needs of the users of the cadastre and abstracts from non-essential aspects, any national legislation is full of. In this paper we investigate how a cadastre supports expropriation and what the necessary interface is. We conclude that the expropriation procedures need access to registration data and a process to register a transfer of ownership effectuated by a court judgment, but no special arrangements that would only serve expropriation procedures. |

| Abstract: Data quality descriptions consider the imperfections found in geographic data. These imperfections are caused by imperfect realizations of the processes that are used to collect, translate, and classify the data. The tiered ontology gives a sensible framework to analyze the data processes and the imperfections they introduce. Decision methods using the data are adapted to some of the imperfections and compensate for them. Additional methods to reduce negative effects of imperfections in the data on decisions are used when necessary. |

| Abstract: The article presents a conceptual framework for computations with imprecise values. Typically, the treatment of imprecise values differs from the treatment of precise values. While precise computations use a single number to characterize a value, computations with imprecise values must deal with several numbers for each value. This results in significant changes in the program code because values are represented, e.g., by expectation and standard deviation and both values must be considered within the computations. It would be desirable to have a solution where only limited changes in very specific places of the code are necessary. The mathematical concept of lifting may lead to such a solution. |

| Abstract: Integration of semantics is a precondition for the integration of data; efforts to integrate or align the semantics expressed in various ontology languages are reported in the literature. The approaches are characterized by the assumptions they make about the known commonalities between the two (or more) sets of classes, described by the ontologies to align, but no-one can proceed without some known common elements in the ontologies. Explicitly introducing the distinctions that differentiate between the classes reduces the number of common concepts that must be established before alignment. A few classes describing water bodies in three languages are used as an example. |

| Abstract: Location Based Services to assist travelers in wayfinding are a prime application for expert system techniques. The use of public transportation leads nearly always to a combination of different services from different providers (multi-modal transportation). Information systems must combine data for the different services and produce advice to navigate in space and to obtain the right tickets, reservations, etc. This information can be seen as two (or more) state-transition diagrams: one for the spatial navigation and one for the business (ticketing, validation, reservation) rules. A (categorical) product combines two state-transition diagrams. The implementation is immediate using an intuitionistic logic reasoner built into the programming language, which infers typing for second order, polymorphic functions and allows their safe execution. The shortest path algorithm in this combined network produces sound advice and reminds the user to acquire tickets and plans the necessary navigation to ticket vending machines, etc. The analysis shows how to specify the connections between the two graphs optionally. The approach combines typical expert system technologies like inference engines with object-oriented programing; recent advances increase the level of reasoning possible during compilation. The use of a high-level programming language with substantial inference power facilitates the formalization of domain knowledge and is a viable alternative to the classical expert system architecture. |

| Karimipour F and Frank AU (2008), "Simplex-Based Spatial Operations". Thesis at: E127 - Institut für Geoinformation und Kartographie; Technische Universität Wien. (6.6.5.) |
| Abstract: Many applications in geosciences need to deal with 3D objects. For this, among other requirements, 2D spatial analyses must be extended to support 3D objects. This extension is an important research topic in GIS and computational geometry. Approaches that extend an existing algorithm for a 2D spatial analysis to work for 3D or higher dimensions lead to different algorithms and implementations for different dimensions. Following such approaches the code for a package that supports spatial analyses for both 2D and 3D cases is nearly two times the code size for 2D. While dimension independent algorithms are an alternative toward generalization, they are still implemented separately for each dimension. The main reason is that each dimension is modeled using a different data structure that requires its own implementation details. In this article we use the list data structure to implement n-simplexes—as a data type that supports spatial objects of any dimension. Primitive operations on n-simplexes become manipulating functions over lists, which are independent of the number and type of the elements. We define spatial analyses as combinations of primitive operations on n-simplexes. Since the primitive operations on n-simplexes have been implemented independently of dimension, the spatial analyses are dimension independent, too. Construction of Delaunay triangulation of nD points, as the basic data structure for many geoscientific researches, is used here as the running example. The implementation results for Delaunay triangulation of some 2D and 3D points are presented and discussed. As a case study the implementations are used to calculate the area and volume of the reservoir of a dam at different water levels, which leads to a level–surface–volume diagram. |

| Hofer B and Frank AU (2008), "Towards a Method to Generally Describe Physical Spatial Processes", In Headway in Spatial Data Handling. LNG&C , pp. 217-232. Springer. |
| Abstract: Spatial processes are the focus of geography and should play a prominent role in geographic information systems (GIS). However, current GIS focus on the static description of properties in space and do not systematically support processes. A general method to describe spatial processes is a prerequisite to including processes in GIS software. This paper outlines an attempt to a general and application independent method to describe processes, limited currently to physical spatial processes. The methodology is based on first modeling a process with a deterministic model. The deterministic models employed here divide the region of interest into blocks and define the influence of the process on each block. The resulting model equations are then related to partial differential equations (PDEs), which are an alternative method for describing processes. Thereby, the qualitative characteristics of processes are identified. A method for describing processes has to be capable of covering the identified characteristics of the processes. As an example the process of diffusion of a contaminant in water is analyzed. The results of this study suggest that this approach allows identifying commonalities among spatial physical processes. These insights can lead to a set of types of processes on which a method to describe spatial processes can be based in the long run. |

| Gaisbauer C and Frank AU (2008), "Wayfinding Model for Pedestrian Navigation", In 11th AGILE International Conference on Geographic Information Science 2008. |
| Abstract: Car navigation systems are now widely used, whereas pedestrian navigation systems have not yet found widespread application. Current pedestrian navigation systems are designed analogously to car navigation systems where the movement of vehicles is constrained by the street network (specifically the lanes). Such a wayfinding model does not reflect the possibilities of pedestrians, where movement is subject to different constrains compared to car drivers. In this paper we describe a new pedestrian wayfinding model that addresses this problem. A graph model is created which consists of decision points and edges connecting them. The free (walkable) space around decision points is expanded to decision scenes where pedestrian movement is modeled in more detail, thus allowing for flexible navigation comparable to unassisted pedestrians. We connect this model with the cognitive needs of users of pedestrian navigation systems and show how our approach incorporates these. |

| Frank AU (2007), "A Case for Simple Laws", In The Mystery of Capital and the New Philosophy of Social Reality. , pp. 288. Open Court. |
| Abstract: I start with de Soto's thesis that the poor of the world would prefer capitalism if they could obtain it at a reasonable price. De Soto points out that poor countries lack the institutions to convert their wealth into working capital. The laws are in place in nearly all countries: there are laws defining ownership in land, land registration, and mortgages. These laws are just notbr>used. Why?br>The laws are in place but that is not enough to allow their usage; multiple cooperating participants are necessary to create capital from valuable assets. When we focus on land, we find that capitalization requires a cooperation of land registration, banking system and courts of law. For effective utilization of the opportunities afforded by the law a general understanding of legal issues is necessary; the legal system must correspond in complexity to general education and specialized legal knowledge available.br>I argue that the concentration on technical issues when advising countries of the third world is misguided; the question is not whether the legal organization is in place, but whether it can be effectively used and at what cost. It seems that some of the legal institutions in the world carry a very high price tag and make them inaccessible to the poor. These institutions create inequality and limit freedom of action which is considered by Amartya Sen as the most important agent to development. The history of European saving and loan cooperatives in the late 18th and first half of the 19th century provide instructive models how to convert wealth into capital. Following these models the creation of capitalization methods should be achieved in the informal sector of the third world. |

| Abstract: The mobile computing is a new revolutionary style of technology that enables us to access information anywhere and anytime. Mobile GIS as an integrating system of mobile computing and some GIS capabilities has fostered a great interest in the GIS field. Although mobile computing has expanded in the past decade, there are still some important constraints the complicate work with a mobile information system. The limited resources in the mobile computing would restrict some features that are available in the traditional computing technology. This chapter attempts to provide a paradigm to treat moving objects in a mobile GIS environment. An idea based on space and time partitioning is suggested. A logic-based framework for representing and reasoning about qualitative spatial relations over moving objects in space and time is proposed. We provide convincing evidence of this theory, by demonstrating how it can provide a framework model of topological relations in space and time. The expressivity power of the proposed framework is shown with some new topological relationships between moving objects and describing the coaching problem in a mobile environment. The latter finds its application in RoboCup championship and battlefield, as well. |

| Abstract: Developing effective urban planning approaches is a major challenge for outdoor and indoor environments. Wayfinding in unfamiliar indoor environments is a prime task which everyone would be encountered. The development of assistive technologies to aid wayfinding is hampered by the lack of reliable and cost-efficient methods providing location information in the environment. We have applied RFID technology as a low-cost and operative approach. Our contribution is the suitable design and placement of digital sign system that can be readily detected by a handheld device. We have simulated the task with an agent-based modeling. The hypothesis of the research is that the wayfinder has a handheld device such as a PDA or a mobile system which receives and responses the signals from digital signs through passive tags. Performance of the simulation showed that the appropriate design of digital signs in an unfamiliar environment would result in a more efficient wayfinding process. |

| Abstract: The quality of GIS data cannot be assessed independently of what it should be used for (''fitness for use''); this assessment requires currently human expert interaction. If the user describes how he uses the data to make a decision, a general method for assessing the quality with respect to their decision is possible. The decision process is divided into two phases, the first producing a decision model and the second uses this model to arrive at the decision. The same decision model is then used to assess the quality of the decision as it derives from the quality of data. Examples for engineering and commercial decisions are given. |

| Abstract: Data quality and ontology are two of the dominating research topics in GIS, influencing many others. Research so far investigated them in isolation. Ontology is concerned with perfect knowledge of the world and ignores so far imperfections in our knowledge. An ontology for imperfect knowledge leads to a consistent classification of imperfections of data (i.e., data quality), and a formalizable description of the influence of data quality on decisions. If we want to deal with data quality with ontological methods, then reality and the information model stored in the GIS must be represented in the same model. This allows to use closed loops sematics to define ''fitness for use'' as leading to correct, executable decisions. The approach covers knowledge of physical reality as well as personal (subjective) and social constructions. It lists systematically influences leading to imperfections in data in logical succession. |

Springer. |
| Abstract: Ontology for geographic information is assumed to contribute to the design of GIS and to improve usability. Most contributions consider an ideal world where information is complete and without error. This article investigates the effects of incompleteness, error, approximation, and uncertainty in geographic information on the design of a GIS restricted to description of physical reality. The discussion is organized around ontological commitments, first listing the standard assumptions for a realist approach to the design of an information system and then investigating the effects of the limitations in observation methods and the necessary incompleteness of information. The major contribution of the article is to replace the not testable definition of data quality as `corresponding to reality' by an operational definition of data quality with respect to a decision. I argue that error, uncertainty, and incompleteness are necessary and important aspects of how humans organized and use their knowledge; it is recommended to take them into account when designing and using GIS. |

| Abstract: All knowledge derives from observation, which is refined and restructured in complex information processes. This article analyzes the information processes with which data or knowledge are transformed from observation to compact, abstract knowledge and decisions. Three ontological tiers for data or knowledge are differentiated: • observations of physical properties at a point (sense data); • formation of object data with summary descriptive properties (granulation) and their mental classification; • conceptual constructions with representations in context that can be communicated. It derives the properties of the imperfections in data from the properties of the information processes and argues that all imperfections in our knowledge must be explained from the properties of the information processes involved. Observations are mainly influenced by random errors that can be modeled by a normal distribution. Granulation can be described by transformations of probability distribution functions (PDF) and mental classification results in fuzzy values. Constructions are free of error within the defining context; better models than supervaluation for the imperfections introduced by change of context are critically needed for semantic data interoperability. |

| Abstract: I argue that level of detail is determined by agents constructing a plan to achieve a specific goal. Influences relevant for the plan are included, others not. This is related to the observation that human decision making is done with imperfect information and the influence of processes are included as they significantly change the outcome. Processes can be classified by the space-time frequency regions they occupy. A goal determines a space-time frequency region and only processes in this regions are relevant. This determines the level of reality related to this goal. |

| Abstract: The web is an immense collection of human knowledge of the world. Humans use this information and cause changes in the world. A separation of reality from the information realm leads to understanding causation as a process starting with decisions in the information realm and the transformation of the decision to material activities that (often amplified by technical systems) change reality. This information causation seems to be the prototypical meaning of causation and material causation as described by the physical “laws of nature” a figure of speech (metaphor), convenient for human thinking. |

| Frank AU (2007), "Navigation System as an Application of the Geodesic in a Discrete Graph" |
| Abstract: Navigation systems help car drivers and pedestrians to find their way in unknown environments; they are probably the most widely used GIS application. GIScience investigates the theoretical foundations for geoinformation. This article describes a series of recent investigations focusing on finding the shortest path in a network represented as graph. This seems comparable to the geodesic in continuous space, but operations in discrete space must rely usually on (agent) simulation. To aid pedestrians in wayfinding and using public transportation systems effectively, they need information not only for their spatial decisions (e.g., buy ticket). These business aspects can be represented as a second graph they navigate. The article shows a novel solution to merge two state-transition graphs using category theory. The resulting formula can be used immediately to program simulation systems or wayfinding programs. |

| Frank AU (2007), "Ontologies for Imperfect Data in GIS", Geoinformation, TU WIen. |
| Abstract: The importance for ontological clarification to design GIS, to structure data in a GIS or to construct usable user interface is well established; ontologies are crucial to extend interoperability from a syntactic to a semantic dimension. The discussion of ontology for GIS always pretends that the data represent reality perfectly, but real data in a GIS can give only an imperfect image of reality. An ontology for imperfect data is necessary, which is an ontology of imperfections in the representation. The analysis starts with a brief review of the ontology typically assumed for a GIS, followed by the description of the ontology of the unavoidable imperfections in the data collected. This covers aspects like partial knowledge, measurement errors, object formation, etc. (restricted to information about physical objects, e.g., data in a GIS with environmental purposes). An ontology of imperfections sheds new light on the quality of information discussion and leads to an operational definition for data quality not based on perfection. Sufficient quality of data is achieved if further improvements would not improve a decision noticeable. This leads to a differentiation of how insufficient data quality can influence a decision. |

| Abstract: In order to achieve interoperability of GIS, the meaning of thepar data must be expressed in a compatible description. Formal methods to describe the ontology of data are increasingly used, but the detail of their definitions are debated.par In this paper I investigate the mathematical structure of formal ontologies as they are the background for ontology languages like OWL, which are increasingly used in GIS. I separate formal aspects of the ontology languages from possible interpretations of the formulae in light of philosophical position. The paper gives formal description of a static and a temporal formalontology. This clarifies what are assumptions (i.e., ontological commitments)and what are consequences of these. A formalized treatment leads to a consistent formal ontology and is the precondition for the integration of ontological descriptions of geographic data. The analysis shows that most of the important restrictions in ontologies can be expressed only in a temporal ontology and they are often related to the question, which processes are included in the temporal ontology. |

| Abstract: The visualization of spatial data has a long tradition in the fields of cartography and geographic information science. There are guidelines for the visualization of topographic and thematic data. Dynamic spatial processes, which are becoming important for the development of geographic information systems (GIS), demand visualization guidelines for processes. The objective of this paper is to find an assignment of dynamic visualization schemes, i.e., animations and dynamic symbols like arrows, to types of processes. Our means to identify the types of processes, which are the basis of this investigation, is the theory of partial differential equations (PDEs). This approach reveals three main types of processes: diffusion-like, wave-like, and steady-state processes. Our results show that for selecting an appropriate visualization schema we need to know whether the process changes over time and what kind of object the process affects. |

| Abstract: The mobile computing technology has been rapidly increased in the past decade; however there still exist some important constraints which complicate the use of mobile information systems. The limited resources on the mobile computing would restrict some features that are available on the traditional computing technology. In almost all previous works it is assumed that the moving object cruises within a fixed altitude layer, with a fixed target point, and its velocity is predefined. In addition, accessibility to up-to-date knowledge of the whole mobile users and a global time frame are prerequisite. The lack of two last conditions in a mobile environment is our assumptions. In this article we suggest an idea based on space and time partitioning in order to provide a paradigm that treats moving objects in mobile GIS environment. A method for finding collision-free path based on the divide and conquer idea is proposed. The method is, to divide space-time into small parts and solve the problems recursively and the combination of the solutions solves the original problem. We concentrate here on finding a near optimal collision-free path because of its importance in robot motion planning, intelligent transportation system (ITS), and any mobile autonomous navigation system. |

| Abstract: A more differentiated structure for the classes Num and related in the Haskell-98 prelude is proposed. It structures operations along the lines of algebraic structures but remains close to and compatible with the current prelude. It allows overloading of the regular arithmetic operations for instances where the corresponding axioms are valid. |

| Abstract: Geographers use spatial reasoning extensively in large-scale spaces, i.e., spaces that cannot be seen or understood from a single point of view. Spatial reasoning differentiates several spatial relations, e.g. topological or metric relations, and is typically formalized using a Cartesian coordinate system and vector algebra. This quantitative processing of information is clearly different from the ways human draw conclusions about spatial relations. Formalized qualitative reasoning processes are shown to be a necessary part of Spatial Expert Systems and Geographical Information Systems. Addressing a subset of the total problem, namely reasoning with cardinal directions, a completely qualitative method, without resource to analytical procedures, is introduced and a method for its formal comparison with quantitative formula is defined. The focus is on the analysis of cardinal directions and their properties. An algebraic method is used to formalize the meaning of directions. The standard directional symbols (N, W, etc.) are supplemented with a symbol corresponding to an undetermined direction between points too close to each other which greatly increases the power of the inference rules. Two specific systems to determine and reason with cardinal directions are discussed in some detail.br>From this example and some other previous work, a comprehensive set of research steps is laid out, following a mathematically based taxonomy. It includes the extension of distance and direction reasoning to extended objects and the definitions of other metric relations that characterize situations when objects are not disjoined. The conclusions compare such an approach with other concepts. |

| Frank AU (2005), "An Empirical Ontology for GIS" |
| Abstract: From the preface: Our world has changed a lot since the classical Greeks started to answer questions of ontology in a systematic way; we have moved from a world where the struggle for physical survival was the foremost concern to a world in which wars are fought on information. Only 20 years ago, ontology was a sub-discipline of philosophy, known to few. Now the term ontology figures in official documents of the European Union and industry— specifically software producers and the information industry— starts research projects on ontology. International standardization organizations are busy with defining “Ontology Languages”. In the information age, the meaning of the information has changed from a “philosophical” debate to a economically important issue. The problem of translation between different languages or professional vocabularies has become important. Different collections of data must be merged to yield valuable information, but this is only possible if the meaning of the data and its encoding is compatible; we observe the differences in vocabulary when we navigate web pages produced by other organisations or ask queries on online databases. In each case, differences in the ontology used and the semantics given to words surface painfully. It is said that the web contains all the information one ever The philosophical debate was mired in the different |

| Abstract: Geospatial Information Systems (GISs) are widely used to support spatially related decisions. However, recent developments in time-dependent data from historical to real time data capture, force GISs to be extended to handle changes over time. Therefore, existing analysis functions have to be lifted from static to dynamic. Most of past efforts in this area have used computational techniques for special purposes. Therefore, using a general concept to establish dynamic capabilities to a wide range of GIS analyses is useful. This is possible through considering GIS elements and analyses as algebraic structures using category theory and its related concepts. It is intended in this paper to define a functor to be used to transform static GIS analysis functions to dynamic ones using higher order (functional) languages. To achieve this objective, some major analysis functions are investigated in this paper and the results will be generalized to the rest, as further steps of this research. |

| Abstract: This research is designed to investigate how remote sensing and GIS can be used in the verification regime of International Treaties-It focuses on the semantic difference and transformation from the goals of a treaty to the observable and verifiable elements. A case study for the Comprehensive Nuclear Test Ban Treaty (CTBT) is presented, demonstrating the potential capabilities for the use of Satellite Imagery and Remote Sensing as a verification technology for the use on an On-Site Inspection (OSI) to narrow down the search area for an unknown underground event or a possible underground nuclear explosion. GIS, by spatially linking different layers of information, acts as a logical analytical tool to overview all the inputs for the verification. In simpler words, it adds up all the clues automatically in order to view the whole situation. For example, in the case of a CTBT verification regime, one has multiple data layers in the GIS database representing various technologies. One layer for the Seismic network and findings, another layer for the radionuclide measurements, and another for the visual observation findings. By overlaying all those layers together and by performing spatial querying in the GIS database, suspicious areas are denoted and identified, and hence an On-Site Inspection can be called to concentrate on those areas at first instead of the whole Inspection Area thus saving time and resources. It is clearly demonstrated that Satellite Imagery and GIS are useful tools and technologies in the verification regime for CTB treaty. However, it has to be understood that satellite imagery and GIS alone are insufficient, they have to be used together with all the other technologies stated in the treaty (e.g. seismic, radionuclide, etc.) and that they can not be the only technology used for the verification. Even though they are a powerful tool, they are strongly dependant on human operators and if the analyst makes a mistake in one of his approaches, the whole azimuth of the results shifts towards a wrong solution. Therefore, Satellite Imagery and GIS when integrated with other technologies acts as a strengthening tool to strengthen or weaken the assumptions but not as a litmus test giving a yes or no answer. |

| Abstract: The decision whether a moving object is inside a polygon or not is a function of time. This is an important and instructive example problem to discuss a general method to deal with temporal data in GIS. Recently, some efforts have been done to handle temporal dimension of our space effectively both in our theoretical and commercial approaches. However, existing commercial GISs have only very limited support for it. In this situation, GI theory is investigating an appropriate solution through formalizing the utilization of time on the basis of mathematical and computer sciences. This formalization is carried out by definition of spatial and temporal concepts, operators, and processes in GI as abstract algebras, which are mapped together using morphisms. The achieved results have to be more advanced by testing different hypothesis. This idea has been implemented for time lifting of issues related to moving objects in this paper and the mentioned approaches are used for hypothesis of integrating static and dynamic point in polygon analysis into a unique algorithm. The conclusions out coming from this work certify validity of these approaches for point in polygon analysis for moving objects. The results will be generalized to the rest, as further steps of this research. |

| Abstract: GI science development has to be served by effective GI theory. Development of GI theory requires clearer characterisation of GI domain which could illustrate real world better and provide a framework for delineation of rational hypotheses. This aim is followed in recent researches by using mathematics as the basis of GI theory. Axiomatic set theory and formal logic is the foundation of this mathematical treatment for study of structures, changes, and spaces in GI domain. While the potential hypotheses require to be modelled into logical structures and be prepared to be evaluated, computer science is adopted as another foundation of GI theory. One of the recent trends in GI theory development is characterizing the real world as functions and utilization of category theory and algebras as the mathematical basis for handling realities and developing hypotheses. Considering this, development of unique and integrated basis for handling static and dynamic GI concepts is one of the hypotheses which are studied in some researches. Their outcomes define theoretical feasibility of defining morphisms between static and dynamic domains known as functors or time liftings. This approach is evaluated for some models and implemented using functional programming languages, however, evaluations are still required for more different characterization of the world. This paper provided one of these evaluations over a topological characterization of convex spaces in real world described by Space Syntax theory. This theory illustrates human settlements and societies as a strongly connected space-time relational system between convex spaces. Such a system is represented by a connectivity graph. Some morphologic analyses are also defined for deriving properties of the graph that illustrate how the space and time are overcome by relational systems and convex spaces. Investigation of temporality in Space Syntax theory resulted that more dynamicity exists in local scales among activities. Then the specific problem of this paper is defined as modelling integrated static and dynamic analyses of an activity / point based problem in local scale in regards with studying how effective they overcome space and time. The derived model is implemented using a functional programming language known as Haskell. While the most important aim of the paper as validity of the time lifting approach for topological models of convex spaces is obtained, some questions about mixed usage static and dynamic data and how the required computation time and memory is increased are formed. |

| Abstract: Pedestrians have often ways in unfamiliar urban environment or in complex buildings. In these cases they need guidance to reach their targets, for example a specific room in a local authorities' building, a counter, or an institute at a university. The goal of location-based mobile services is to provide such guidance on demand (anywhere, anytime), individually tailored to the actual information needs and presented in preferred forms. This project is focusing on the information aspect of location-based services, i.e. on the user's task at hand and the support of the user's decisions by information provided by such a service. Specifying a task ontology will yield context-dependent conceptualizations, activities, and references to directions from the user's perspective. These specifications will allow to:br>- select appropriate sensor data and to integrate data when and where needed,br>- propose context-dependent routes, fitting to partly conflicting interests and goals,br>- select appropriate communication method in terms of supporting the user guiding by various multimedia cartography forms.br>To test and to demonstrate the approach and results this project takes a use case scenario - guiding visitors to institutes of the Technical University Vienna - and develops a prototype. |

| Abstract: This paper models the decision process when selecting among different datasets the one most suitable for a task. It shows how metadata describing the quality of the dataset and descriptions of the task are used to make this decision. A simple comparison of task requirements and available data quality is supplemented with general, common-sense knowledge about effects of errors, lack of precision in the data and the dilution of quality over time. It consists of two steps: first, compute the data quality considering the time elapsed since the data collection; and second, assess the utility of the available data for the decision. A practical example of an assessment of the suitability of two datasets for two different tasks is computed and leads to the intuitively expected result. |

| Abstract: A cadastre is a system of major importance for economy and planning. A cadastre provides data on land. It is the basis for legal aspects like ownership as well as fiscal aspects like taxation of land. The cadastre also provides data for planning assignments (for example, boundaries of constructions, land use, and soil). Storage and update of these data require a complex system that had been developed in Austria during more than 100 years. Understanding, using, and improving a cadastre requires knowledge on the cadastral processes. The problems a cadastre must solve are important to understand the needs for a cadastre. It is also important to understand the processes of a cadastre to see how a cadastre works. These processes define the way a cadastre handles data and what prerequisites the data must fulfil to be accepted by the cadastre. Improving a system requires analysis of the processes. The user wants to work with a cadastre. He needs processes that meet his demands. Improving the efficiency of the processes, therefore, improves the efficiency of the cadastre directly because then the user will be satisfied (his work will be done better or faster). The paper discusses the tasks of a cadastre. The starting point is the needs of users (owners, government and many others). The needs define the tasks and the data needed to fulfil the tasks. The next step is the definition of the processes to fulfil the tasks. The paper then formalizes these processes. Finally, implementations for two different cadastral systems prove the general validity of the processes. |

| Abstract: This study analyzes the surveying activities followed by the Austrian Federal Office for Metrology and Surveying (BEV). The BEV, a subordinate agency of the Austrian Federal Ministry of Economics and Labour, accomplishes two main categories of activities within the surveying area. One activity is concerned with the Fiscal Cadastre, which deals with the storage and administration of parcel boundaries at the national level and maintenance at the regional level. The second activity is the Topographic and Mapping Survey, which deals with the production and maintenance of topographic data with national coverage. The study concludes that the Austrian Cadastre, namely the fiscal and ownership cadastre, is cost effective. The contributions of the users to the maintenance of the cadastre, via property and transfer tax, fees for registration of ownership change and mortgage, and revenues from cadastral data sale, seem to be adequate according to the nature and purpose of the cadastral system, i.e. the security and protection of the land owners’ property rights. The Topographic Survey covers broader and diverse data needs, from the public to the private sector, having defence a central role in the production of topographic data. The free access to topographic data seems to be appropriate, given that 75% of the users belong to the public sector. Additionally, topographic data access can contribute to the economic growth in terms of job creation, business opportunities, R&D growth, etc. The biggest impact of this recommended change will be at the level of the SME and the citizens, ending up with the confinement of these data to big business and government. This method of making public data available free of charge is believed to have contributed in the U.S. at the beginning of the 90s to the growth of the American economy, which has affected, in last instance, the tax revenues. |

| Abstract: In Europe National Mapping Agencies (NMAs) are generally parts of the public sector. But why does the public sector intervene in an economic activity as, for example, in the production and collection of geodata? Currently NMAs are experiencing transformation pressure in Europe. Political and economic authorities want to achieve an industry with a more competitive structure. In industries, like the production and collection of geodata, with high levels of sunk costs, it is not evident that privatization will help to increase competition.br> |

| Abstract: The least-angle strategy is a common wayfinding method that can be applied in unknown environments if the target direction is known. The strategy is based on the navigator's heuristic to select the street segment at an intersection which is most in line with the target direction. To use this strategy, the navigator needs to know the angles between the target direction and the street segments leading out from the intersection. If the direct view to the target is blocked and the target vector cannot be perceived, the target direction that is needed for the decision process is based on the agent's believed position and orientation (estimated through path integration). The agent's believed position and target direction are distorted by human errors in estimation of distances and directions, mainly affecting the path integration process. In this paper we examine how human estimation errors of distance and rotation influence the decision behavior in the wayfinding process in an unknown street environment. To demonstrate the geometrical consequences for a specific test case, we use a simulated software agent which navigates in a simulated street environment |

| Abstract: The simulation of human behavior in space is an extremely interesting and powerful research method to advance our understanding of human spatial cognition and the interaction of human beings with the environment. Multi-agent systems are an emerging computing paradigm for the construction of such simulations. During the last two years, we have used multi- agent simulations for three different investigations of spatial and cognitive questions: - use of signage in airports to guide travelers to the gate, - communication with maps, - linkage between physical reality and the cadastral (legal) system. In this paper we will report on these efforts. We first discuss the concept of multi-agent systems and explain the special type of multi-agent system used for simulation of cognitive and spatial situations. The following three sections each review one of the three simulations we have constructed. The last section identifies the similarities in these approaches and lists questions we hope to investigate in the future with this method. |

| Abstract: Philosophers have proposed many different ontologies. Despite hundreds of years of effort, it has been impossible to reconcile the differences between them and to establish a single, widely accepted ontology. For practical purposes a consistent and comprehensive ontology is necessary: information systems which manage adequate descriptions of the world must be constructed on the basis of some ontology, even if this ontology is never explicitly described. This was not clear in the early years of information systems and many practical problems were discovered which could later be traced back to inappropriate ontological assumptions. The connection between information systems and ontology was at the foundation of the CYC project (Lenat, Guha et al. 1990) and has since gained substantial acceptance among theoretical and practical thinkers in information systems (Guarino 1998; Sowa 1998). The construction of re-usable ontologies (Frank 1997) has become an interesting, rapidly growing business and ‘ontologist’ is an acceptable job description in forward-looking IT companies. The design of Geographic Information Systems, which cover information about objects and properties in the world with respect to their location (Longley, Goodchild et al. 1999) involves ontologies too. Indeed, such systems are ontologically more demanding than ordinary administrative information systems. They span a much larger diversity of kinds of things: from the description of the elevation of the surface of the earth with a regular grid of points to the description of the natural land cover (woods, fields, etc.) and morphology (mountains, valleys, etc.). They also include man-made features like roads and buildings as well as artificial boundaries between a range of different sorts of political and administrative units (Smith 1995), etc. There is no ready -made single ontology to cover all of these most diverse aspects of reality. Therefore we propose here the construction of an ontology consisting of several coordinated tiers. An ontology constructed from tiers can integrate different ontological approaches in a unified system. In particular, it can merge a plenum, continuous space ontology with Aristotle’s ‘natural kind’ ontology of objects. We can also integrate the ontology of ‘social reality’ described by Searle (1995). It seems possible also to overcome some of the differences between competing proposals, differences which we can understand as motivated by the examples the authors have in mind. From our practical experience, we have learned that a single ontology, which applies to all situations and the most diverse kinds of phenomena in the world or in our imagination, is not achievable. Therefore we propose here an orderly integration of otherwise contradictory proposals. I am not interested here in terminological discussions, and I use terms like ‘ontology’ in a generic way; Guarino (1997) has shown the many different uses of the term by different authors and I do not want to add to this list. My approach is empirical and stresses our daily experience in interacting with the world as a source of knowledge to build ontologies. The goal is a computational model of an ontology, which can be used for the construction of information systems. The remainder of t his paper first gives an overview of the tiers and then discusses each of them in turn. It sketches how a computational model of ontology could be built and draws some conclusions about its usefulness. |

Unfortunately in real situations rules for consistency constraints are not so clear, and inconsistent ontologies are common place, not least in geographical information, covering as it does a much wider realm than many other information systems I have suggested elsewhere 5-tiers of ontology for GIS. Such an ontology can integrate different ontological approaches in a unified system. In this paper the relation of the 5-tier ontology and consistency constraints is explored, and it is shown that different constraints are appropriate to different tiers. |

| Abstract: People have to find their ways through cities, through buildings, along streets and highways, using public transportation, etc. In order to do so, they have to be provided with adequate wayfinding information, which is communicated to them from different sources and through different modes of communication. The analysis of such interplay is important if one wants to simulate human wayfinding in a cognitively plausible way. Such simulation of wayfinding tasks helps to determine where people face wayfinding difficulties, why they face them, and how wayfinding information and the design of wayfinding environments have to be changed in order to communicate better to the user.In this work we use an agent-based approach to simulate multimodal communication of wayfinding information within a computer system. In general, an agent can be anything that can perceive its environment through sensors and act upon that environment through effectors (Russell and Norvig 1995). In our case we simulate a cognizing agent finding its way through an airport based on information communicated to it via different modes. The restriction to the well-defined microworld of an airport reduces the enormous complexity of modeling the world and users' intentions. It therefore makes it possible to investigate the different modes of communication in detail. In order to do so, we develop a formal model, which fixes the meaning of the conceptual process model for wayfinding. The formal model is represented in a functional language and it is therefore possible to check its consistency and simulate test cases (such as finding the way from the check-in counter to gate C54) (Raubal and Worboys 1999).The cognizing wayfinding agent is based on three modules that deal with perception, decision, and action. A cognitive schema (Neisser 1976) internal to the agent guides these processes. It includes information about the task and the goal, and a minimum of wayfinding strategies and commonsense knowledge necessary for the agent to perform the task. Most of the wayfinding information in an airport is communicated visually, either through signs, screens, and maps, or through architectural features. Arthur and Passini (1992) termed this ``environmental communication'' and argued that the built environment and its parts should function as a communication device. In our agent-based simulation we use the concept of affordances to describe the kinds of knowledge that agents derive from the world by means of visual perception. Affordances (Gibson 1979) are possibilities for action with reference to the agent. Information (such as from signs) is necessary for the agent to decide upon which affordances to utilize. The task description from the cognitive schema directs visual perception in such a way that the agent samples only task-relevant information and affordances.Auditory sources are another important aspect for communicating wayfinding information in an airport. Such sources are non-cognizing objects of the environment, such as loudspeakers, or other cognizing agents, such as passengers or employees of the airport. The auditory mode of communication plays an especially important role during emergency situations when directions for passengers are given through speakers, and also for blind people who need to receive information through channels other than visual perception. We model communication with other cognizing agents within a multi-agent framework (Weiss 1999), focusing on the direct exchange of information based on the idea of spatial communication with maps. Here, information is communicated from a map-making agent who explores the environment and collects information, which he uses to construct a map of the area, and a map-using agent who acquires this map to gain knowledge, which he uses to navigate in this environment (Frank 2000).As an example for the integration of multimodal communication of wayfinding information, we further investigate location based navigation services using mobile phones. Agents can be given information through textual instructions on the client display, through verbal instructions, or via symbols and digital maps. The mode(s) of presenting wayfinding instructions depend(s) on the agent profile (e.g., handicapped vs. non-handicapped) and the task. Finding one's way in an airport uses a different set of cognitive abilities than navigating through a city. The presentation of wayfinding information depends also on the user interface of the client device. Well-designed user interfaces facilitate human-computer interaction, i.e., the communication process between user and computer.Future work with an agent-based approach to simulate multimodal communication of wayfinding information will also have to include vestibular, tactile, and proprioceptive sources of information. Furthermore, the results of our simulation method have to be compared to the performance of human subjects in the real world. |

| Abstract: Interoperability is crucial for the future viability of the European GIS industry. The industry however seems to lack sufficient organisation and access to the international interoperability specification. Full participation and integration of European interests into the process is the best chance to gain competitiveness. This fact is recognised, among others, by the European Commission, who put much effort into stimulating developments in this field. Both Directorate General III (Industry) and Directorate General XIII (Telecommunications, Information Market and Exploitation of Research) from the European Commission are funding projects in the domain of GIS development, under respectively the ESPRIT and the GI2000 programmes. This paper focuses mainly on the GIPSIE project, which promotes interoperability for the European GI community. Also, some attention will be given to related European GI projects such as Panel-GI and the European Spatial Metadata Initiative (ESMI). |

| Abstract: Maps are very efficient to communicate spatial situations. A theoretical framework for a formal discussion of map production and map use is constructed using a multi-agent framework. Multi-agent systems are computerized models that simulate persons as autonomous agents in a simulated environment, with their simulated interaction. A model of the process of map production and map use is constructed based on a two-tiered reality and beliefs model, in which facts describing the simulated environment and the simulated agents' beliefs of this environment are separated. This permits to model errors in the persons' perception of reality. |

| Dieberger A and Frank AU (1998), "A City Metaphor to Support Navigation in Complex Information Spaces", Journal of Visual Languages and Computing. Vol. 9, pp. 597-622. |
| Abstract: A major problem in modern information systems is to locate information and to re-find information one has seen before. Systems like the Word-Wide Web are heavily interlinked but do not show structures that help users to navigate the information it contains. The use of appropriate navigation metaphors can help to make the structure of modern information systems easier to understand and therefore easier to use. We propose a conceptual user interface metaphor based on the structure of a city. Cities are very complex spatial environments and people know how to get information, how to reach certain locations in a city, and how to make use of the available infrastructure etc. Cities provide a rich set of navigational infrastructure that lends itself to creating sub-metaphors for navigational tools. A city metaphor makes this existing knowledge about a structured environment available to the user of a computerized information system. We first focus on several properties of future user interfaces (or user interface metaphors) that will distinguish them from current systems, like the richness of information or the use of visualizations to show the structure of information spaces. We also describe the strengths and problems of spatial user interface metaphors. Then we describe the structure of the information city metaphor, its structuring and navigation metaphors and what we see as its main advantages and problems. We further describe a few scenarios of how an Information City might work. Finally we compare implementing this metaphor using either a textual or graphical virtual environment or a combination. |

| Abstract: Simplicial Complexes are used to model topology in Geographic Information Systems (GIS). Line intersection is an essential operation to update them. We introduce a finite-resolution line intersection method, called Zero Order Intersection, and apply it to simplicial complexes.Any reliable implementation of a line intersection algorithm has to address the limitations of a discrete computational environment. If handled improperly, finite representation can cause drifting lines and similar effects in otherwise topologically consistent data. The Zero Order Intersection method is designed to avoid such inconsistencies. Its application to simplicial complexes results in the Discrete Simplicial Data Model which guarantees consistency and reliability of topological queries within a GIS. |

| Abstract: Formal specifications are difficult to read. Executable specifications allow to see the behavior of the specified objects and help the domain specialist to detect errors quickly. We present here a method which allows to write axiomatic specifications which can be executed and discuss the limitations in expressive power imposed by the restriction to constructive axioms and how it can be circumvented. The method results from practical efforts to formalize the meaning of object types for Geographic Information Systems. If such data are shared between organisations, differences in the semantics become apparent and formal methods for their definition become necessary. Most formal methods are based on first order languages. Software engineering often uses algebraic methods, but tools practically used for data exchange standard definitions are restricted to signatures and do not capture the behavior of the operations. We present here an algebraic approach using a functional programming language which includes specification of behavior and results in executable code. The case used here to demonstrate the problem is the base for an ontology of spatio-temporal databases. The world consists of objects, which have identity. Identifiers, objects and world classes are defined as algebras with axioms. Executable models for these are given. This environment is necessary to describe objects with operation, when the essential part of the definition is the change an object can undergo. It would be difficult to write this in a first-order language. The focus is on the capabilities of the executable functional programming language Haskell to formalize algebraic specifications; the issue is, how much of an algebraic specification can be expressed formally in an executable language and how much must be relegated to the implementation models (expressed in the same language). The example shows that a very large part - and most of the important behavior - can be captured in axioms for abstract classes. |

| Frank AU, Volta GS and McGranaghan M (1997), "Formalization of Families of Categorical Coverages", IJGIS. Vol. 11(3), pp. 215-231. |
| Abstract: Categorical coverages are popular for the presentation of thematic data in cartographic form and have gained widespread use. Routines for their preparation are included in most GIS software. Categorical coverages are simple to implement and easy to understand. The popularity of the categorical coverage is closely related to the intuitive rules that determine its behavior. This paper presents a formalization of these rules based on the concepts of a partition of space and the refinement of such partitions of space. A family of categorical coverages is defined as all categorical coverages that can be produced from a data set through aggregations of categories. It is shown that categorical coverages are partially ordered by ’refinement’ of partitions. This ordering is preserved in the mapping from the ordering of the partition of the attribute domain to the partition of space. This formalization is not only useful for implementors of GIS, but the list of possible operations and their properties is the base for the design of a user interface to produce and manipulate categorical coverages. The thematic definition of categorical coverages is directly related to the cartographic rendering. Changes in the thematic definition, i.e. changes of the map legend, can be automatically propagated to the rendering. Limitation of cartographic rendering, e.g. resolution of the screen, limits the presentation of the result. These influences from the rendering cannot automatically be translated into changes in the subdivisions of the categories. This may explain why good graphical presentation is still an art and the production of thematic maps is not fully automated. |

| Frank AU (1997), "Geographic Information Business in the Next Century", In Third Joint European Conference on Geographical Information, JEC-GI'97. Vol. 1, pp. 13-22. |
| Abstract: Geoinformation business today is seen mainly as traditional consulting, often by surveyors and cartographers. In most countries, the collection of spatial data, especially property surveying, is organised as a technical consultancy centered around understanding the data collection techniques. In the years to come, demand for property surveying, often the major activity of surveyors, will not likely increase. Geoinformation, however, can be used in various contexts and for many different activities - it is a field with a large growth potential. The same data, once collected, can be used by and sold to several organisations. These growing business opportunities are open to all: town administrations, utilities, surveyors, planners, and geographers, may profitably sell Geoinformation products from their own data bases. Designing and marketing a Geoinformation Product requires an approach which does not start from the data collection methods but from the user’s needs: The Geoinformation Product must provide an information useful and valuable to the user. Content, appropriate data quality and presentation must meet the user’s expectations. The price must be commensurate with the benefits the users derive from the information. The price of a product is not linked directly to the cost of its production, thus the cost of a Geoinformation Product, i.e. digital geographic data, is not linked directly to the cost of collecting and providing the information. To sell the same data to different user groups to be used for different purposes requires product differentiation, in order to reap maximal benefits. The specialists for Geoinformation are challenged by the new market opportunities to sell data for car navigation support, marketing and distribution services, emergency services, and, last not least, leisure activities like travelling. |

| Abstract: Ontology is the science of objects. It is an ancient discipline, which has recently been rediscovered, and overhauled, for the purposes of Artificial Intelligence. Ontology has been concerned with the properties of objects, with their modes of existence and with questions such as how they can be divided in parts and how they fill space.This presentation takes the position of a user of ontologies. It will seek to show not only that there is a 'production of ontologies' in the research literature, but also that these ontologies are useful and can be used. The paper will concentrate on the latter two issues, focusing on a particular area of application, namely that of Geographic Information Systems (GIS). It will answer the question, how can ontologies be used and how can they contribute to building better information systems? This will mostly be done by showing how the lack of a consistent ontology in a system causes difficulties for its users.The paper will conclude with a set of recommendations as to how ontologies can be made more useful and how the connection between the producers and consumers of an ontology can be structured to make the exchange of ideas more effective. I will also list a number of broad general directions and specific topics which I believe may yield useful contributions both from a scientific and from an engineering point of view. This paper is built on a simple metaphor: ontologies are products and are sold in the international supermarket of AI research. In this supermarket, consumers look for ontologies which fulfill their particular needs. They select ontologies to describe the entities in their application domain and the chosen ontologies must form a consistent ensemble. Unfortunately, contradictions and other inconsistencies may become apparent as one seeks to implement the information system. In consequence, producers of ontologies must put clear labels on the products on the shelf, indicating the advantages and disadvantages of each ontology and indicating also potential conflicts with other ontologies: ``Truth in labeling for ontologies!'' |

| Abstract: Modeling GIS or applications of GIS with object-oriented tools is difficult for the practitioners. There are numerous issues involved, from technical to conceptual. In this case study the deed registration system is studied using formal, object-oriented tools. The level of formalism reveals particular properties of ‘administrative logic’, which is less strict than the standard assumptions for database query processing. The deed registration system used in the USA and the property registration system in Europe appear as different solutions to a similar problem. How much do they have in common? A formal modeling approach will demonstrate the functional similarities, due to the similar social demands, and the differences owing to different historic developments. The approach taken here starts from the most fundamental operations of a property registration system. It is found that the models are comparable and the rules are fundamentally similar. The checks for a valid transfer of ownership are quite similar (but differ in detail even within the USA), but the time of checking is different. A Continental title registration system checks documents when they are received, whereas the US counterpart registers first without checking and only later the validity is checked by a prospective buyer's lawyer. Several results from this study can be generalized to other administrative GIS applications: - The question of identity plays a primary role and several types of ‘identities’ may be hierarchically nested. - Administrative rules are less strict than database logic on what constitutes an entity or an identifier (the ‘unique name assumption’ is maintained only within a context).. - Administrative time for a registry is a simple ordered scale. These results are of practical importance for the design of GIS software which includes a ‘land ownership layer’ and should be applied in countries with different property registration systems. It shows the designers of property registration software, what can be built into a general, widely usable system and where a system must leave scope to adapt to local rules. The study was motivated by efforts to design a property registration system for a reform country. In this situation, one has to understand how social demands and legal rules relate to the technical solution. To design formal models is the best way to achieve this. |

| Abstract: Using hierarchical methods for spatial reasoning is a popular research topic. Hierarchical spatial data structures, especially quadtrees, are used in many implementations of GIS and have proved their efficiency. Operations on hierarchical spatial data structures are effective to compute spatial relations, but do not automatically imply Hierarchical Spatial Reasoning. Hierarchical spatial reasoning is using coarser, less detailed representations to compute an approximative answer if the quality of the approximation is sufficient. Hierarchical spatial reasoning is closely related to computing approximative results and estimation of their errors. This paper explores two spatial reasoning operations and deduces a general definition of ‘hierarchical spatial reasoning’. Although the examples are very simple - computation of area and intersection - and applied to a raster representation, the definition appears general. Compared with other definitions it captures much of the essence of hierarchical spatial reasoning. This sets the framework in which general rules when hierarchical spatial reasoning can be employed may be deduced. Hierarchical data structures are useful for hierarchical reasoning, but they can be transformed to a more efficient ‘incremental hierarchical structure’, e.g., an incremental quadtree. Then, incremental hierarchical spatial reasoning algorithms use previously computed values to compute the next approximation and are therefore as efficient as a direct calculation with the same error bound. |

| Abstract: Geographers use spatial reasoning extensively in large-scale spaces, i.e.,spaces that cannot be seen or understood from a single point of view.Spatial reasoning differentiates several spatial relations, e.g.topological or metric relations, and is typically formalized using aCartesian coordinate system and vector algebra. This quantitativeprocessing of information is clearly different from the ways humans drawconclusions about spatial relations. Formalized qualitative reasoningprocesses are shown to be a necessary part of Spatial Expert Systems andGeographic Information Systems.Addressing a subset of the total problem, namely reasoning with cardinaldirections, a completely qualitative method, without recourse to analyticalprocedures, is introduced and a method for its formal comparison withquantitative formulae is defined. The focus is on the analysis of cardinaldirections and their properties. An algebraic method is used to formalizethe meaning of directions. The standard directional symbols (N, W, etc.)are supplemented with a symbol corresponding to an undetermined directionbetween points too close to each other which greatly increases the power ofthe inference rules. Two specific systems to determine and reason withcardinal directions are discussed in some detail.From this example and some other previous work, a comprehensive set ofresearch steps is laid out, following a mathematically based taxonomy. Itincludes the extension of distance and direction reasoning to extendedobjects and the definitions of other metric relations that characterizesituations when objects are not disjointed. The conclusions compare such anapproach with other concepts. |

| Frank AU (1996), "Radial Categories Applied to Object-Oriented Modeling - A Case Study for a Property Registration System", In 1st Int. Conference on Geographic Information Systems in Urban, Environmental and Regional Planning. |
| Abstract: Design of GIS applications must model current systems, including their administrative and legal aspects. The standard concentration on the static data structure in GIS — as captured with database design tools — is insufficient and an object-oriented approach is necessary to include the operations carried out. The combination of operations and data structure in a modeling tool is crucial to properly capture complex administrative or legal processing of documents, including the temporal aspects. This is clearly visible in the application selected here, namely real estate property registration, where one cannot succeed without modeling space and time. Object-Oriented Modeling is the widely acclaimed method in software engineering. It is used for design and programming, but did not reduce the software crisis. The theory of object-orientation is simple, but the application to practical cases points to more difficulties than expected. The primary concept of object-orientation corresponds well with cognitive principles, but the details of practical object-oriented languages add confusion. The non-trivial case study is used here to point out the issues and to propose an approach which is in line with human cognition. First the object-oriented concepts are revisited in the context of a class based functional programming language. It stresses the separation of behavior from implementation inheritance and allows design and rapid prototyping in the same language. Human cognition uses radial categories with a central prototype. This is used to start the design of the property registry. Several refinement steps are then applied. This approach and the set of tools used allows to separate the code of refinement steps and result in very compact, formally checked code. |

| Abstract: Spatial data are being collected at an increasing pace, with photogrammetry and remote sensing serving as the most productive data collecting disciplines. At the same time, markets for spatial information are emerging world-wide. Still too often, however, there is a mismatch between the demand and supply of spatial information: data being collected and offered sometimes do not meet the expectations of potential buyers. The malfunctioning of spatial data markets has many reasons, ranging from the fact that users are often unaware of existing data to the difficulties in interpreting and processing spatial data once they have been bought, to institutional and legal obstacles. A major technical reason is the lacking usability of data collections. The presentation addresses the issue of usability and discusses the widely proposed remedy of metadata. It concludes that the most effective step toward usable spatial data is not to document data collections, but to modularise them into small manageable units and packaging them with suitable operations. This vision of future spatial information services is currently being pursued under the heading of ``Open GIS''. |

| Abstract: Geographic Information Systems manage data with respect to spatial location and that data is presented graphically as a map or sketch. A database of objects with some geometric properties is used to render these objects graphically for different tasks. Typically these tasks require graphical presentations at different levels of detail, ranging from overview screens to detailed views [Herot et al., 1980]. Practically a base map is stored and its scale changed graphically. Without major distortions, only changes to twice or half the original scale are feasible by simple numeric scale change. A function to draw cartographic sketches quickly and in arbitrary scales is needed. We propose a multi-scale hierarchical structure where renderings of spatial objects with increasing detail are stored: a directed acyclic graph (DAG). These are used to compose a topographic map at a particular scale. We assume that the object renderings for the DAG already exist. Methods to select objects for rendering are based on the importance of the object for a particular task and on the principle of equal information density. We propose a method for determining information density, namely measuring the ink content of the map. |

| Abstract: Modeling in GIS is limited to the standard geometric data models: vector and raster. Not all problems can be expressed in these models and extensions are requested by applications. To determine precise requirements for extensions, case studies are beneficial. In this paper the focus is on the expressive power required for design applications. A significant part of the road design task is used as a case study to explore if constraint databases can contribute to the solution. Road design is a suitable example for GIS design applications, as road design in the past used topographic maps and map analysis methods.The general design task for the layout of a highway is presented: Find the technically feasible alternative road layouts between two points. Select the best for further assessment. Given are the design parameters of the road (design speed, minimal radius of curves, maximum slope) and information about the terrain (land cover, elevation, geology). The problem is sufficiently complex to pose substantial research questions, but simple enough to be tractable. Three observations result from this case study:-Constraint databases can be used to model continuos variables, and therefore space (not only discrete points in space),-Representing space with a Delaunay triangulation leads to conceptual simplifications,-The original constraint of the road design problem, which are of a higher degree, can be linearized to make the problem computationally tractable.A test implementation is underway, exploring the performance aspects of the use of constraint databases for road design. |

| Abstract: This paper focuses on spatial information derived from the composition of two pairs of cardinal directions (e.g., North and North-East) and approximate distances (e.g., near and far), i.e., given the approximate distances a1 (A, B) and a2 (B, C) and the cardinal directions c1 (A, B) and c2 (B, C), what are a3 (A, C) and c3 (A, C)? Spatial reasoning about cardinal directions and approximate distances is challenging because distance and direction will affect the composition. This paper investigates the dependency between qualitative and quantitative inference methods for reasoning about cardinal directions and approximate distances. Cardinal directions are based on a 4-sector model (North, East, South, West), while approximate distance correspond to a set of ordered intervals that provide a complete partition (non-overlapping and mutually exclusive) such that the following interval is greater than or equal to the previous one (for example, ``far'' would extend over a distance that is at least as great as ``medium.'') We ran comprehensive simulations of quantitative reasoning, and compared the results with the ones obtained from quantitative reasoning. The results indicate that the composition is robust if the ratio between two consecutive intervals of quantitative distances is greater than 3. |

| Abstract: Menschen verwenden Hierarchien, um konzeptionelle Modelle der Realität zu vereinfachen und damit die gestellten Aufgaben effizienter durchführen zu können. Dabei wird der Raum hierarchisch strukturiert. Dies erleichtert die Durchführung komplexer Aufgaben mit sehr großen Datenbeständen. Eine der wichtigsten Forschungsfragen im Bereich des Räumlichen Schließens ist das Verständnis, wie kognitive räumliche Strukturen gestaltet sind und verwendet werden.Hierarchisches räumliches Schließen ist jeder Inferenzprozeß über den Raum, welcher die Hierarchie zur Unterteilung der Aufgabe oder des Raumes anwendet. Dazu braucht man:1. eine hierarchische Struktur des Raumes,2. eine Anzahl von Regeln, welche aussagen, wie die Struktur zum Schließen verwendet wird, insbesondere wann und wie zwischen den Ebenen gewechselt wird,3. einen Vergleich der ``Korrektheit'' von Resultaten und der Effizienz der hierarchischen Strukturierung mit der nicht-hierarchischen Methode.Diese Komponenten stellen die Grundprinzipien des hierarchischen räumlichen Schließens dar.Im besonderen wird hier die Wegesuche in großen Straßennetzen als Spezialfall untersucht. Ziel dieser Studie ist es, durch Formalisierung von großen Straßennetzen ein konzeptionelles Modell der Hierarchie für den Raum und dafür einen effizienten Algorithmus zur Wegesuche abzuleiten und Heuristiken für das räumliche Schließen festzulegen. Methoden und Resultate ergeben die den Heuristiken zugrunde liegende Theorie. Es ist zu erwarten, daß ihre Anwendung in Automobilnavigationssystemen eine effektive Wegesuche in großen Straßennetzen ermöglicht. |

| Abstract: In Geographic Information Systems a function to draw cartographic sketches quickly and in arbitrary scales is needed. This calls for cartographic generalization, a notoriously difficult problem. Efforts to achieve automatic cartographic generalization were successful for specific aspects, but no complete solution is known, nor are there any expected within the immediate future. In practical applications, a base map is stored and its scale is changed. Without major distortions, only changes to twice or half the original scale are feasible by simple numeric scale change. Everything beyond this requires adaptation of symbols, selection of objects, placements of labels etc. Extending ideas of hierarchies or pyramids, where representations of the same objects at different scales are stored, a multi-scale, hierarchical spatial model is proposed. Objects with increasing detail are stored in levels and can be used to compose a map at a particular scale. Applied to the particular problem of cartographic mapping, this results in a multi-scale cartographic tree. The same concept can be used equally well for other applications, which require rendering of objects at different levels of detail. The structure of the multi-scale tree is explained. It is based on a trade-off between storage and computation, replacing all steps which are difficult to automate by essentially redundant storage. The dominant operation is 'zoom', which moves towards a more detailed level, intelligently replacing the current graphical representation with the more detailed one, appropriate for the selected new scale. Methods to select objects for rendering are based on the principle of equal information density. Principles of possible implementations are presented. |

| Abstract: There is a strong request for GIS to include temporal information. Most efforts currently are addressing the incorporation of time qua calendar time. Events are dated according to the ordinary time and calendar, which are effectively measurements on an interval scale. Temporal information available only as relative order between events cannot be incorporated in this framework. Clearly knowledge about temporal order without measurement on the time scale is less precise but nevertheless useful. Human beings use qualitative temporal reasoning all the time. Qualitative ordinal information about events is typically encountered in archeology, urban development etc. where precise dates for events are not known but the relative order of events can be deduced from observations. Even in legal proceedings about parcel data, ordinal relations are often all what matters. These are among the disciplines which have asked for the inclusion of facilities to deal with temporal data in GIS. This paper gives specifications for ordinal temporal reasoning using qualitative methods. It differentiates between different time models, each having slightly different properties: models with or without events at the same time, models with total or partial order. It discusses the introduction of tolerances (without recourse to measurements of an epsilon value) and how it affects reasoning. The semantics are given as formal specification, expressed in an algebraic notation which can be executed. An example from a parcel subdivision is used throughout and results from various computations are compared with human logical deduction. |

| Abstract: Geographic information systems (GIS) have become a widely used technology for managing spatially referenced information in the private and public sectors. The rapid growth of the market for GIS technology and digital spatial data raises some crucial economic issues. While past GIS implementations were primarily concerned with hardware and software capabilities, the focus of attention is now shifting to issues of effective system use by individuals and organizations. Among these issues are the usability of GIS and the cost of data, including their maintenance. This paper presents an analytical investigation of such issues in the context of GIS data acquisition by manual map digitizing at a national surveying and mapping agency. |

| Abstract: There seems to be some uncertainty in the GIS literature regarding the use of the words data model and data structure. There is a clear understanding of these notions in the database literature and it is possible to define analogous terms for GIS: geometric data model and geometric data structure. Geometric data model is used to describe a formalized abstract set of spatial object classes and the operations performed on them. Geometric data structure is then the specific implementation of a geometric data model which fixes the storage structure, utilization, and performance. Humans organize their spatial perceptions using concepts that can be defined as spatial concepts to denote an informal or not directly implementable conceptual structure used to understand space. Examples are given to clarify the theoretical discussion. |

| Abstract: Sound engineering approaches to user interface design require the formalization of key interaction concepts, one of them being metaphor. Work on interface metaphors has, however, been largely non-formal so far. The few existing formal theories of metaphor have been developed in the context of natural language understanding, learning, or reasoning. We propose to formalize interface metaphors by algebraic specifications. This approach provides a comprehensive formalization for the essential aspects of metaphorical user interfaces. Specifically, metaphor domains are being formalized by algebras, metaphorical mappings by morphisms, and image-schemas by categories. The paper explains these concepts and the approach, using examples of spatial and spatializing metaphors. |

| Abstract: Before an intelligent discussion of cartographic databases can start, we have to clarify the necessaryterminology: ``What is a cartographic database and how is this notion related to other similar terms,GIS in particular?'' We stress the importance of the database concept and detail some technicalaspects. The contents of a map can be conceptualized in different forms, from a purely graphical viewpoint to a highly structured collection of data, each set of concepts carrying with it its appropriate set of operations. After establishing the differences between GIS and cartographic data base, wethen go on to explore potential relations between a GIS and a cartographic database. Of specialinterest is how a GIS and a cartographic database for the same region are related and how one canbenefit from the other by establishing links between multiple representations of the same real objects. Technically speaking, the cartographic database is a `materialized view' of the GIS; therefore methods like triggers and active database concepts need to be explored for their suitability. The majorproblems in designing cartographic data structures are a lack of understanding of the structure ofmaps and the process that produces them, and the lack of model for map reading. The linkagebetween data structures and map structure is stressed and research topics outlined. |

| Abstract: A GIS is not just a collection of maps stored in a computer, but a database that should correctly model a particular region of the world. Since the world is changing continuously, GIS applications require that the data collection to be updated. Every GIS is, by definition, a database that manages spatial data and includes facilities to update its data so it continues to reflect the current situation. But only a GIS that includes ``time'' and ``space'' in its model of reality is often called a ``temporal GIS,'' which contains the current information and keeps the data that describe the previous states and when they were applicable. A temporal GIS must answer ``when-and-where-'' questions, such as: ``what were the boundaries of New York City in June, 1908?'' ``Where were the forest areas in New England in 1880,'' or ``which properties owned John Doe in Baltimore from August 1981 to June 1988.'' When GIss include time, they can really demonstrate the enormous advantage of a database that models reality compared to a conventional collection of printed maps. |

| Abstract: The PANDA database management system was designed for non- standard applications which deal with spatial data. It supports an object-oriented program design with modularization, encapsulation, and reusability, and can be easily embedded into complex applications, such as spatial information systems or cartographic expert systems. It is presented how complex objects and their operations are defined. A layered structure on top of the programmer’s interface provides object operations which include potentially complex consistency constraints. |

| Abstract: Several methods have been proposed for the storage of geometric properties in Geographic Information Systems, but many are based on the storage of metric data (coordinates) and analytical geometry. Because of the well-known limitations of implementations of the algebra of computer real numbers, such as incidence and inclusion during affine transformations. We propose an approach in which topological relations are separately recorded and independent of metric positions. The method is based on the use of simplices, which are the simplest polyhedrons of each dimension. The zero- dimensional simplex is the point, the one-dimensional one line, etc. In order to allow for non-straight lines as connections between points, we actually use cells, which are the homeomorphic image of simplices. In order to store topological relations, we use two completeness principles: Completeness of incidence and completeness of inclusion. We can show that in such a geometric configuration topology is invariant to affine transformations, independently of the method selected for recording metric information. For formal treatment we form a multi-sorted algebra (abstract data types). The axioms for this algebra must be selected such that the above-mentioned principles are maintained as invariants. We rely on an arbitrary method to learn about the topological relations initially. This “oracle” may use the calculation of a distance and a threshold, query the user or decide randomly, but it cannot influence the consistancy of the resulting geometry, as it is consulted only if the same information was not previously available and thus cannot lead to an inconsistent situation. Reasonable performance is expected, as this method imposes a ‘neighborhood’ structure on the data. All operations use and change only data of objects in immediate proximity. Databases suitable for handling spatial data should permit clustering of data by proximity. |
