This new stable release adds hundreds of new features, support for the
latest GIS data formats, and includes new translations for many languages.
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
as well as many mirror sites.
