Open Source GIS History
In XX and XXI century, a series of other desktop and server Open Source GIS projects were started:
- geospatial libraries: PROJ.4, Geotools, Geoserver, TerraLib, Boost.Geometry
- Desktop GIS: GRASS GIS, SAGA GIS, uDIG, gvSIG,ILWIS
- Web mapping/WebGIS: deegree, UMN MapServer, MapGuide Open Source
- geostatistics software: gstat, R Project for Statistical Computing
1978 - Map Overlay and Statistical System (MOSS). A pioneer vector-based geographic information system (GIS) developed by the U.S. Department of Interior. MOSS is still available to download (ftp://ftp.blm.gov/pub/gis/). Dr. Carl Reed has written an article about MOSS history.
since 1982-today - GRASS (Geographical Resources Analysis Support System) is the earliest Open Source GIS which reached production status and supported both raster and vector data. It was originally developed from 1982 to 1995 by the U.S. Army Corps of Engineers, since then by the international GRASS Development Team. Initially published as public domain software, its license was changed to GNU GPL (General Public License, see www.gnu.org) in 1999.
1983 - PROJ4 library development
1995 - UMN MapServer project started. In 2002 MapServer gets Python support.
1998 - deegree development started with an OGC Simple Features implementation. The project was renamed from JaGo to deegree in 2002.
1998 - GDAL/OGR development started. Python support was added in 2000.
1999 - GRASS GIS source code moved from manual management into CVS
2000 - Atlantis Scientific launched OpenEV project
2000 - JTS Topology Suite project was initiated in Fall 2000. JTS 1.0 was released in February 2002 and version 1.1 in March 2002.
2001 - OSSIM initial revision in CVS
2001 - PostGIS started
2001 - GeoNetwork opensource started as GeoNetwork, later renamed to GeoNetwork opensource.
2002 - Intevation,Gmbh starts Thuban projects
2002 - Quantum GIS initial revision in CVS
2002 - GEOS initial revision in CVS
2002 - AVPython for ArcView 3.x published as FOSS
2003 - Release of Mapbender under the GNU GPL license
2003 - gvSIG was started
2005 - MapGuide Open Source
2006 - Mapbender gets first bits in CVS
2006 - OpenLayers started
2007 -  ILWIS became open source
2008 - GRASS GIS runs natively also on MS-Windows
1992: "Open GRASS Foundation" (OGF)
1994: OGF was re-structured as the Open Geospatial Consortium (OGC)
2006: Open Source Geospatial Foundation (http://www.osgeo.org) established whose mission is to support and promote the collaborative development of open geospatial technologies
