GRASS GIS 6.2.2 released

The GRASS Development Team announces

GRASS GIS 6.2.2 released 16 July 2007

We are happy to announce that a new bugfix version of GRASS GIS has been released today. This release fixes a number of bugs discovered in the 6.2.1 source code. It is primarily for stability purposes and adds minimal new features. Besides bug fixes it also includes a number of new message translations and updates for the help pages.

This release is particularly important for Ubuntu users due to a number of Bourne shell script fixes. Other highlights include a new location creation GUI with EPSG search and further maturation of the GRASS 6 GUI, vector, and database code. These improvements have been backported from the GRASS 6.3 development branch where new development continues at a strong pace of approximately one code commit every hour, including major work being done on an all new cross-platform wxPython GUI.

The Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) combining powerful raster, vector, and geospatial processing engines into a single integrated software suite. GRASS includes tools for spatial modeling, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. It also provides the capability to produce sophisticated 4D presentation graphics and hardcopy maps.

GRASS is currently used around the world in academic and commercial settings as well as by many governmental agencies and environmental consulting companies. It runs on a variety of popular hardware platforms and is Free open-source software released under the terms of the GNU General Public License.

GRASS is a proposed founding project of the new Open Source Geospatial Foundation. In support of the movement towards consolidation in the open source geospatial software world, GRASS is tightly integrated with the latest GDAL/OGR libraries. This enables access to an extensive range of raster and vector formats, including OGC-conformal Simple Features. GRASS also makes use of the highly regarded PROJ.4 software library with support for most known map projections and the easy definition of new and rare map projections via custom parameterization. Strong links are maintained with the QGIS and R Statistics projects with integrated GRASS toolkits available for each.


Platforms supported by GRASS

GNU/Linux, Mac OS X/Darwin, Microsoft Windows (native using MinGW or with full UNIX support via Cygwin), Sun Solaris (SPARC/Intel), Silicon Graphics Irix, HP-UX, DEC-Alpha, AIX, BSD, iPAQ/Linux and other UNIX compliant platforms. GRASS runs on both 32 and 64 bit systems with large files (>2GB) supported by many key modules.

Software download/CDROM

The new source code is available now and binary packages for major operating systems will be published shortly.

For details on GRASS software capabilities please refer to: http://grass.itc.it/intro/general.php, the previous GRASS 6.0.0, GRASS 6.2.0, and GRASS 6.2.1 release announcements, and the Wiki collaborative help system.

We are always looking for testers, code developers, and technical writers to help us maintain and accelerate the development cycle. The GRASS GIS project is developed under the terms of the GNU General Public License (the GPL) in the open 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.
