QGIS Features
QGIS is a cross-platform (Linux, Windows, Mac) open source application with many common GIS features and functions. The major features include:
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 (http://postgis.refractions.net/) and SpatiaLite,
most vector formats supported by the OGR (http://www.gdal.org/ogr/ogr_formats.html) library*, including ESRI shapefiles (http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf), MapInfo, SDTS and GML (http://en.wikipedia.org/wiki/Geography_Markup_Language).
raster formats supported by the GDAL (http://www.gdal.org/formats_list.html) library*, such as digital elevation models, aerial photography or landsat imagery,
GRASS (http://grass.itc.it/) locations and mapsets,
online spatial data served as OGC (http://www.opengeospatial.org/)-compliant WMS (http://en.wikipedia.org/wiki/Web_Map_Service) , WMS-C (http://wiki.osgeo.org/wiki/WMS_Tile_Caching) (Tile cache), WFS (http://en.wikipedia.org/wiki/Web_Feature_Service) and WFS-T
(http://en.wikipedia.org/wiki/Web_Feature_Service)
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
Create, edit and export spatial data using:
digitizing tools for GRASS (http://grass.itc.it/) and shapefile formats,
the georeferencer plugin,
GPS tools to import and export GPX (http://www*****ografix.com/gpx.asp) format, convert other GPS formats to GPX, or down/upload directly to a GPS unit
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
Publish your map on the internet using the export to Mapfile capability (requires a webserver with UMN MapServer (http://mapserver.gis.umn.edu/) installed)
Adapt Quantum GIS to your special needs through the extensible plugin architecture
