My homepage is work in progress. It is a place to test and communicate ideas.

It contains:

• A nearly complete list of my publications for download.
• Unpublished writings for discussion, mostly as blog and some longer texts. The pieces are alternatively available as pdf in article format, which makes printing and reading for some more comfortable.
• The last versions of the lecture notes I used at TU Wien (dated 2005)
  • Practical Geometry, The Mathematics for GIS.
  • Empirical Ontology for GIS, A computational ontology for space, time, matter and information.
  • Feasibility and Realization of Geoinformation Products - in german (2014)

The homepage is produced by my daino program and should adapt to any screen width - thanks to w3c templates - and will be further improved with images.

Directories with more related texts:

• Contacts and curriculum vitae of various length
  Contacts and curriculum vitae of various length
• Longer texts
  Essays and other longer texts. Some were written as ongoing observations, e.g. on the COVID pandemia, the experience with the house in Volterra (both in German) and some other more essay like, e.g. on poetics (in German), on the design of the engine to produce this homepage (in English).
• Students and colleagues
  A list of students I advised, colleagues and friends.
• List of lecture notes and books with their abstracts
  Lecture notes (a.k.a. scripts) for download and titles of books published with Gerastree Editions to be ordered from Amazon.
• New Series of Blog Contributions
  My old Blog directory contains too many contributions I wrote years ago; much of it is not relevant anymore and not maintained. I plan to make some of it available again in the future. Here I start a new series for small contributions related to the day (longer texts go to the directory Essays).
• Presentations
  Slides from presentations.
• Index for publication lists
  My (most complete) list of publications, with links to downloads
