Yesterday, March 2nd 2010, the annual FOSSGIS conference got off to a good start and for the first time in its’ history covers a four day program. One major innovation this year is the prominent participation of the OpenStreetMap project, that is dedicated to producing free geodata. Through this participation a gap that was perceived by many is being closed since any information systemprofits from accurate and up-to-date data. terrestris has helped to shape this years’ program, as we did in past years too, by submitting a number of talks. Marc Jansen gave the keynote speech of the conference titled “HTML 5, ECMAScript 5 and the cloud – Potencials for future WebGIS applications”, while Till Adams held a much noted talk on “There is no alternative to OpenLayers ….?”. All talks are in german only unfortunately but will be available for download at the end of the conference here.
