Mike’s looking at some open source GIS solutions to move from ArcGIS. He’s been trying to do everything for “free” using Fedora Linux and he’s been blogging about it. Some really interesting thoughts come to mind about how to get support from an open source community vs. a corporate support model such as ESRI. If you want to help him out I’m sure he’d be happy to get some comments about what to do next while he compiles QGIS, GRASS and GDAL.
