Quantum GIS (QGIS) is a cross-platform Geographic Information System (GIS). It offers support for vector and raster formats, including spatially enabled tables in PostgreSQL using PostGIS, common GIS vector formats such as Shapefiles, and geo-referenced rasters (TIFF, PNG, and GEOTIFF). Many plugins are available to dynamically add new functionality. Viewing of GRASS layers (vector and raster) is provided by a plugin. GRASS vector layers can be edited in QGIS.
QGIS Features

QGIS is a cross-platform (Linux, Windows, Mac) open source application with many common GIS features and functions. The major features include:

1.View and overlay vector and raster data in different formats and projections without conversion to an internal or common format.

Supported formats include:

?spatially-enabled PostgreSQL tables using PostGIS and SpatiaLite,
?most vector formats supported by the OGR library*, including ESRI shapefiles, MapInfo, SDTS and GML.
?raster formats supported by the GDAL library*, such as digital elevation models, aerial photography or landsat imagery,
?GRASS locations and mapsets,
?online spatial data served as OGC-compliant WMS or WFS;

2.Create maps and interactively explore spatial data with a friendly graphical user interface. The many helpful tools available in the GUI include:

?on the fly projection,
?print composer,
?overview panel,
?spatial bookmarks,
?identify/select features,
?edit/view/search attributes,
?feature labeling,
?vector diagram overlay
?change vector and raster symbology,
?add a graticule layer,
?decorate your map with a north arrow, scale bar and copyright label,
?save and restore projects

3.Create, edit and export spatial data using:

?digitizing tools for GRASS and shapefile formats,
?the georeferencer plugin,
?GPS tools to import and export GPX format, convert other GPS formats to GPX, or down/upload directly to a GPS unit

4.Perform spatial analysis using the fTools plugin for Shapefiles or the integrated GRASS plugin, including:

?map algebra,
?terrain analysis,
?hydrologic modeling,
?network analysis,
?and many others

5.Publish your map on the internet using the export to Mapfile capability (requires a webserver with UMN MapServer installed)

6.Adapt Quantum GIS to your special needs through the extensible plugin architecture.
