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.

Here are some key features of "Quantum GIS":
Support for spatially enabled PostGIS tables
Support for shapefiles, ArcInfo coverages, Mapinfo, and other formats supported by OGR
Raster support for a large number of formats
Identify features
Display attribute tables
Select features
GRASS Digitizing
Feature labeling

What's New in This Release:
On the fly projection support to automatically project layers from different coordinate systems
Map Composer for creating map layouts
Toolbox for running GRASS tools from QGIS. The toolbox can be easily customized to add additional tools
Handling of spatially enabled tables and views in PostgreSQL has been greatly improved. QGIS can now load any table in the database that contains a geometry column
PostgreSQL views containing a geometry column can be viewed in QGIS
Raster graphing tool to produce a histogram for a raster layer
Raster query using the identify tool allows you to get the pixel values from a raster by making it the active layer and clicking on the point of interest
User preferences provides customizable settings for the digitizing line width, color, and selection color
New symbols for use with point layers are available from the layer properties dialog
Spatial bookmarks allow you to create and manage bookmarks for an area on the map. Bookmarks are persistent and global; meaning they are available for all projects
Measure tool allows you to measure distances on the map with both segment length and total length displayed as you click
GPX loading times and memory consumption for large GPX (GPS) files has been drastically reduced
Many enhancements to the digitizing tools have been made, including the ability to capture data straight into PostgreSQL/PostGIS, and improvements to the definition of attribute tables for newly created layers
The Raster Georeferencer plugin can be used to generate a world file for a raster. The plugin allows you to define known control points in the raster coordinate system. Once enough control points are defined, the world file can be generated and the raster properly displayed in QGIS or other GIS applications
Improvements to the Mapserver export tool
