GRASS 6.2.1 is a new stable release which fixes several bugs discovered in the 6.2.0 source code. This release is solely for stability purposes and adds no new features. Besides bug fixes it also includes a number of new message translations, updates for the help pages, and will better handle errors caused by missing or incorrectly installed support software. It also introduces a new 3D raster module which was left out of the last release due to time constraints.

The Geographic Resources Analysis Support System (GRASS) is a Geographic Information System (GIS) used for spatial modeling, visualization of both raster and vector data, geospatial data management and analysis, processing of satellite and aerial imagery, and production of sophisticated presentation graphics and hardcopy maps. GRASS combines powerful raster, vector, and geospatial processing engines into a single integrated software package.

The GRASS GIS project is developed under the terms of the GNU General Public License (the GPL) by volunteers the world over. GRASS differs from many other GIS software packages used in the professional world in that it is developed and distributed by users for users, mostly on a volunteer basis, in the open, and is given away for free. Emphasis is placed on interoperability and unlimited access to data as well as on software flexibility and evolution rate. The source code is freely available allowing for immediate customization, examination of the underlying algorithms, addition of new features, and fast bug fixing.

GRASS is currently used around the world in academic and commercial settings as well as by many governmental agencies and environmental consulting companies.
