The Spoken Tutorial Effort for QGIS has being contributed by Dr. Plugins can geocode using the Google Geocoding API, perform geoprocessing functions, which are similar to the standard tools found in ArcGIS, and interface with PostgreSQL/PostGIS, SpatiaLite and MySQL databases. Plugins written in Python or C++ extend QGIS's capabilities. QGIS integrates with other open-source GIS packages, including PostGIS, GRASS GIS, and MapServer. Multiple formats of raster images are supported and the software can georeference images. QGIS supports both raster and vector layers vector data is stored as point, line, or polygon features. QGIS functions as geographic information system (GIS) software, allowing users to analyse and edit spatial information, in addition to composing and exporting graphical maps. QGIS (previously known as Quantum GIS) is a free and open-source cross-platform, desktop geographic information system (GIS) application that supports viewing, editing, and analysis of geospatial data.
