QGIS is a user-friendly Geographic Information System (GIS) distributed under the GNU General Public License. It is an official project of the Open Source Geospatial Foundation (OSGeo). It is compatible with Linux, Unix, Mac OS X, Windows and Android and includes many vector, raster, database and feature formats.
QGIS is a project focused on volunteering. We accept contributions in the form of code participation, return or bug fixes, contributions to documentation, outreach and support to other users on our mailing lists and on gis.stackexchange.com. If you want to actively support the project, you can find more information in the development menu and on the QGIS Wiki.
The QGIS project is always looking for (user) stories to share case studies on its website. We solicit the testimony of institutions, universities, local authorities and companies recounting their QGIS experience to solve their problems on a daily basis. Please contact the QGIS community if you would like to share your experience.
The stories should follow a simple structure of a reasonable size of about 800 words, including one or two screenshots.
A short introduction with the context of the society / institute / local authority / university (approximate length of 200 words). Project or application chapter detailing the use of QGIS (approximately 400 words in length plus screenshots). Conclusion showing benefits and positive feedback from QGIS usage (approximately 200 words in length).
Manages the spatial extension of PostgreSQL, PostGIS.
Supports a large number of vector data formats (Shapefile, ArcInfo covers, Mapinfo, GRASS GIS, etc.)
Also supports a large number of matrix layer formats (GRASS GIS, GeoTIFF, TIFF, JPG, etc.)
One of the features of QGIS is to use it as the graphical interface of the GRASS SIG. It is thus possible to use all the analysis power of this software in a more user-friendly work environment. The GRASS features are optional, and pass through an extension module (plug-in).
In addition, QGIS has - by default - many modules, including:
A GPS data read / write module, based on the GPSBabel program.
A georeferencing module, which allows to "stall" an image (aerial view, typically) in a terrestrial reference.
In addition, since version 0.9, it has a real Python-based scripting engine. This makes it possible to create modules more simply than in C ++, but also to build real applications. This possibility goes through PyQt, the bridge between Python and the Qt4 graphics library.
