The GRASS Development Team announces
We are pleased to announce that a new stable version of GRASS GIS 6.4.1 has been released. This release fixes some bugs discovered in the 6.4.0 source code and a few new features (over 560 updates to the source code with respect to 6.4.0 have been added). As a stable release 6.4 will enjoy long-term support.
GRASS 6.4 brings a number of exciting enhancements to the GIS. Our new wxPython graphical user interface (wxGUI) is debuted, Python is now a fully supported scripting language, and for the first time since its inception with a port from the VAX 11⁄780 in 1983, GRASS runs natively also on a non-UNIX based platform: MS-Windows.
A detailed description of changes can be found in the GRASS 6.4.1 Release News page.
For a comprehensive list of changes see the 6.4 ChangeLog file.
The Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) providing powerful raster, vector, and geospatial processing engines in 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 presentation graphics and hardcopy maps. GRASS has now been translated into twenty languages and supports a huge array of data formats.
GRASS is a founding member of The Open Source Geospatial Foundation (OSGeo), a non-profit legal entity which has enjoyed extraordinary growth. We expect that this formal infrastructure will guarantee that the GRASS community will be well supported and vibrant far into the future.
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.
The GRASS software including over 400 built-in analysis modules and 100 community supplied add-on modules and toolboxes can be downloaded for free from the main GRASS website at http://grass.osgeo.org, or from many local mirrors worldwide. In addition to the extensive documentation which comes with the software, our Wiki help system contains a wealth of user supplied tips and tricks, tutorials, and guides.
Users are encouraged to study, customize, extend, improve, and (if necessary) diagnose and modify the inner workings of any part of the program. We believe that scientific progress depends on the reproducibility of results, which in turn depends on the unhindered ability of the user to know, evaluate, double-check, and learn from all algorithms and methodologies used in the process of their work.
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, the BSD family, iPAQ/Linux and other UNIX compliant platforms. GRASS runs on both 32 and 64 bit systems with large data file (>2GB) support for most key modules.
The new source code is available now along with selected binary packages.
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.
