Quantum GIS

Quantum GIS is an open source Geographic Information System (GIS) that allows you to create maps and visualise spatial data.

A GIS allows you to store and analyse geographic data. Whether you want to illustrate the relief of a mountainous area, create an interactive map or show catchment areas, Quantum GIS is the tool you will need.

Download the desktop application – available for Windows, Linux and Mac – to start uploading and visualising your geographic data. Quantum GIS also offers a browser, a server and a web front end to facilitate your data viewing experience.

Quantum GIS also offers spatial analysis, including map algebra, terrain analysis, hydrologic modeling and network analysis.
