Open Source GIS
Open Source GIS [Last update: 12/8/2013 - About 350 projects listed.] This effort represents an attempt to build a complete index of Open Source / Free GIS related software projects. In addition to those alphabetized here, many great projects are listed at the end and will be integrated soon. And this will all move to a proper database. The definition of GIS is kept loose to encompass a broad range of projects which deal with spatial technology.
