My homepage is work in progress. It contains a

• nearly complete list of my publications for download.
• unpublished writings for discussion, mostly as a blog, written during the past years and collected here.
  
• the last versions of the scripts 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)

I will collect here professional and private information. My homepage should serve as a place where I test new ideas and communicate them to my friends.

The presentation uses the layout pioneered by Edward TufteIt builds on tools like tufte-css, tufte-css-pandoc and pandoc-css.

and runs with Pandoc. Pandoc makes it possible to produce from the same text (in Markdown format) the HTML for the web presentation and a pdf, which is usually easier for reading a paper copy.

The text should adapt to the screen widthThanks to w3c templates

- and will be further improved with images.

The presentation requires some more fine tuning and fixing differences in formatting, which emerged over the years of writing.
