gvSIG Desktop – Open Source Geographic Information System

gvSIG Desktop is a powerful, user-friendly, interoperable GIS used by thousands of users worldwide.

It is easy to work in a variety of formats with gvSIG Desktop, vector and raster files, databases and remote services. The software offers a variety of tools to analyze and manage your geographic information.

gvSIG Desktop is designed to be an easily extensible solution, allowing users to improve the software application and develop tailor made solutions.
