GVSIG

'gvSIG' is a multilingual, open source geographic information system (GIS) that can handle both vector and raster data. It features basic editing tools for the creation and maintenance of vector or raster spatial data on a variety of file formats, including remote data sources. gvSIG is being actively developed in Java by IVER Tecnologías under the GNU General Public License (GPL) [1]. Its name is a Spanish abbreviation that stands for ''Generalitat Valenciana. Sistema de Información Geogràfica''.
gvSIG was started in 2003 when the Regional Council for Infrastructures and Transportation (CIT) of Spain proposed the development of software for the management of geographic information. The private enterprise IVER Tecnologías won the proposal and is now developing the software together with the Valencian Autonomous Government and the Jaume I University of Castellón [2].
Currently gvSIG runs on Windows, Linux, and Mac OS X operating systems. It supports many open and proprietary standards of geospatial data. A plugin system allows for expandability and compliance with many standards of the Open Geospatial Consortium (OGC) making it compatible with many other GIS software and data.

Standards

gvSIG supports the following data formats:

★ Vector formats: shapefile, DXF, DGN, DWG

★ Raster formats: ECW, MrSID, JPEG, jp2, TIFF, geoTIFF, PNG, GIF
gvSIG is able to read remote data with Open Geospatial Consortium (OGC) standards:

★ Web Map Service (WMS)

★ Web Feature Service (WFS)

★ Web Coverage Service (WCS)
gvSIG also offers support for remote data from ESRI’s ArcIMS.
The WMS has been tested with MapServer, DeeGree and GeoServer; the WCS with MapServer; and the WFS with MapServer and GeoServer.
There are plugins available that enable gvSIG to read ERDAS IMG files and also connect to PostGIS and MySQL databases.
