“The GIS guy needs to know that there is more to GIS than Esri”.
I am working with MapInfo and talked about QGIS yesterday. Today I came across OrbisGIS which appears to be designed to solve environmental modelling questions. This appealed so I downloaded it. Expect my verdict in the future. http://www.orbisgis.org
I also read an academic journal article on open source GIS. It was nice to read a journal after more than a year away from academia, even if I couldn’t be happier atm to not be locked in the library reading hundreds of them like most students are right now. It’s a little old (2008) but a good summary. http://terragis.net/docs/presentations/sstein_foss_desktop_gis_overview.pdf
