Open Source Geospatial '05, an international conference addressing geospatial data technologies developed by or of relevance to the Open Source community, will be held June 16-18, 2005 in Minneapolis, Minnesota USA. The conference will bring together the MapServer, EOGEO, and OSGIS communities, but seeks to be more broadly inclusive. A committee has been working since July to design a program with elements that will interest participants from the novice to the expert. The conference strives to build on the successes and enthusiasm generated by previous, related meetings.
