Open Source Geospatial Foundation – OSGeo www.osgeo.org Mission: To support the development of open source geospatial software and promote its widespread use. Founding projects (constituted in February 2006): GDAL/OGR, GeoTools, GRASS GIS, Mapbender, MapBuilder, MapGuide Open Source (Autodesk), MapServer, OSSIM Since Feb 2008: GRASS (and others) are official members Motivation: More that 200 GFOSS projects worldwide... … need for selection and organization: User oriented!
