Desktop Raster/Vector Processing

GRASS/GDAL/OGR - Data Crunching Both Raster and Vector support Very powerful tool set (similar to ArcINFO/ArcGRID) Traditionally Poor GUI, but getting better Very fast Cross platform

QGIS/GDAL/OGR – Data Viewing/Editing Both Raster and Vector support Nice GUI Cross platform QGIS can integrate with GRASS
