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
