The conference for Free and Open Source Software for Geographic Information Systems – FOSSGIS (conference language is german) will take place in Heidelberg next week from Tuesday to Thursday (05 – 07.04.2011). We would like to invite all interested persons to attend this conference since an abundance of information concerning open source and GIS will be presented there. terrestris will share a stand with its partner OpenGeo and will contribute to the programme with a number of talks and workshops. The office in Bonn will be staffed but most of our developers will attend the conference in Heidelberg.
