GRASS GIS on CDROMGRASS GIS (Geographic Resources Analysis Support System) is a GNU GPL copyrighted Geographical Information System (GIS) with raster, topological vector, image processing, and graphics production functionality that operates in the UNIX environment through a graphical user interface and shell in X-Windows.
Are you getting mad of downloading this software through internet?
You can order the GRASS GIS CDROM. The CDROM contains always the current
version of GRASS 4.2.1/5.0beta - the CDROM will be produced on demand
to let you participate in ongoing GRASS development. By that, you will always
get the latest version.
