Background

Theodor Förster (1980) is a PhD candidate at ITC's Geo-Information Processing department (GIP) since end of 2005. His PhD research covers the technical generalization aspects within the framework of the Ruimte voor Geo-Informatie (RGI) 002 research project "Generation and use of base maps for integrated querying of digital physical development plans" (www.durpondergronden.nl). In this context he is mostly interested into web service standards for geo-processes and geo-data and the formalization of generalization operators. The PhD study is supervised by Jantien Stoter and Menno-Jan Kraak.

In 2005 he received his Diploma in Geoinformatics at the University of Muenster, Germany (http://www.uni-muenster.de). Before and after graduation he worked at the Institute for Geoinformatics in Muenster (http://ifgi.uni-muenster.de) for different projects related to GI web-application development.

He is active member of the 52north open source initiative (www.52north.org) and is leading the development of the 52north Web Processing Service (52n WPS). Besides that he is participating in the standardization of geo-processing services at OGC.
