Asunto: [Freegis-list] Celebrating 30 years of GRASS GIS!

Press release 
29 July 2013 Today marks 30 years of GRASS GIS development 

Today the Free Software community celebrates the 30th birthday of GRASS GIS ! 
GRASS (Geographic Resources Analysis Support System) is a free and open source 
Geographic Information System (GIS) software suite used for geospatial data 
management and analysis, image processing, graphics and map production, spatial 
modeling, and 3D visualization. GRASS GIS is currently used in academic and 
commercial settings around the world, as well as by many governmental agencies 
and environmental consulting companies. GRASS GIS can be used either as a 
stand-alone application or as backend for other software packages such as QGIS 
and R geostatistics. It is a founding member of the Open Source Geospatial 
Foundation ( OSGeo ) and can be freely downloaded at . 

30 YEARS OF GRASS GIS!Brief history 

In 1982, Lloyd Van Warren, a University of Illinois engineering student, began 
development on a new computer program based on a master's thesis by Jim 
Westervelt that described a GIS package called LAGRID – the Landscape 
Architecture Gridcell analysis system. Thirty years ago, on 29 July 1983, the 
user manual for this new system titled " GIS Version 1 Reference Manual " was 
first published by J. Westervelt and M. O'Shea. The software continued its 
development at the U.S. Army Corps of Engineers Construction Engineering 
Research Laboratory (USA/CERL) in Champaign, Illinois; and after further 
expansion version 1.0 was released in 1985 under the name Geographic Resources 
Analysis Support System (GRASS) . The GRASS GIS community was established the 
same year with the first annual user meeting and the launch of GRASSnet, one of 
the internet's early mailing lists. The user community expanded to a larger 
audience in 1991 with the "Grasshopper" mailing list and the introduction of 
the World Wide Web. The users' and programmers' mailing lists archives for 
these early years are still available online . 
In the mid 1990s the development transferred from USA/CERL to The Open GRASS 
Consortium (a group who would later generalize to become today's Open 
Geospatial Consortium -- the OGC ). The project coordination eventually shifted 
to the actual international development team made up of governmental and 
academic researchers and university scientists. Reflecting this shift to a 
project run by the users, for the users, in 1999 GRASS GIS was released the 
first time under the terms of the GNU General Public License (GPL). A detailed 
history of GRASS GIS can be found at . 

Since these early days GRASS development has progressed and grown, adjusting 
with and often at the forefront of new technologies as they became available. 
Today GRASS's software development is maintained by a team of domain experts as 
visualized in this beautiful new video animation which stylistically details 
the codebase evolution and modifications from 1999 through to 2013 , up to and 
including the latest GRASS GIS 6.4.3 stable release. 30 years of active growth: 
where are we now? 

Recent versions of GRASS GIS come with exciting new features like: 

    * A new modern graphical user interface complete with integrated 
workflow-wizards and interactive tools, 
    * A new Python interface to the core C geoprocessing libraries, permitting 
Python developers to create powerful new modules in a quick and simple way, 
    * Fully-fledged topological vector support for editing and tools for 
topological analysis and data cleaning, 
    * Hundreds of new modules to analyze raster and vector data of all scales 
and types, with hundreds more contributed in an active community repository, 
    * Support for massive data processing (e.g. relevant for LiDAR processing) 
and Large File Support (> 2GB, 64-bit files on 32-bit systems), 
    * A codebase portable to all of today's major Operating Systems, 
    * Installed on everything from low-power dataloggers and field laptops to 
high performance Grid Engines and TOP500 supercomputers. 

GRASS GIS is currently developed by a global team of around twenty core 
programmers, plus numerous add-on contributors, testers, and translators. 
Overall, more than seventy core developers have worked on the code in the past 
thirty years, making over fifty-thousand modifications to the code. All the 
while, hundreds more have provided peer review and improvements to algorithms 
and documentation while using GRASS GIS in professional, educational, and 
research contexts. Where to next? 

Development on GRASS GIS continues with as much energy and interest as ever. 
Version 6.4.3 has been released as a birthday present . Parallel to the 
long-term maintenance of the GRASS 6 stable series, effort is well underway on 
the new cutting-edge major release, GRASS GIS 7 , bringing with it many new 
features, modules, enhancements, and cleanups. As in the past, the GRASS GIS 
community is open to any contribution, be it in the form of programming, 
documentation, testing, financial sponsorship or any other form of support.
