[GRASS-user] Scientific Comparison between GRASS and Proprietary Remote Sensing/GIS Software

[Jan Hartmann]

Carlos, is it possible to get a copy of your article? It is important in 
"selling" GRASS and Open Source GIS in my University environment. That's 
not easy, to say the least, so I can use any help I can get.
