New stable release of the GIS combining powerful raster, vector, and geospatial processing engines
discovered in the 6.2.1 source code. This release is solely for
stability purposes and adds no new features. The default Graphical
User Interface has been further stabilised, and the LIDAR processing
tools and Linear Reference System support significantly
improved. GRASS 6.2.2 also includes a number of new message
translations, and updates for the help pages.
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
