The conference Geoinformatik 2010 took place from March 17 to 19 in Kiel at the Christian-Albrechts-University. A comprehensive and eclectic agenda induced approximately 400 people to visit the conference. Although the talk by terrestris regarding “OpenLayers, Geoext and MapFish” was located in the last session before the end of the conference on a Friaday it was attended by about 60 participants. The subject matter concerning interactive cartography on the internet using Web 2.0 techniques is a hot topic at this point in time, so the comparatively high number of listeners is attributed to this fact.
