GRASS stands for Geographic Resources Analysis Support System.
Commonly referred to as GRASS, this is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies.
It is the most complete free GIS application available. It can be used both in command line and GUI mode. Integration with Quantum GIS provides further user-friendliness. Its ability to work in conjunction with the free statistical application R (by means of the package "spgrass6") is particularly interesting for research applications.
GRASS versions exist for Windows and Mac, but as it is mainly developped for Linux, it is recommanded to use it on a Linux system or through a virtual machine.
gvSIG is a tool oriented to manage geographic information. It is characterized by a user-friendly interface, with a quick access to the most usual raster and vector formats. In the same view it includes local as well as remote data through a WMS, WCS or WFS source.
It is aimed at users of geographic information, whether professionals or civil servants (city councils, councils, regional councils or ministries) from any part of the world ( at the moment its interface is in Spanish, Valencian, English, Basque, Gallego, Czech, Chinese, French, German, Italian, Romanian, Polish and Portuguese), in addition to being free.
Given its Free Software nature (open source) it is highly interesting for the international community of developers and, in particular, for university settings due to its R&D&I component. In fact, special emphasis has been placed on the expansion of the project so that potential developers can easily expand the functions of the application, as well as develop completely new applications from the libraries used in gvSIG (as long as they comply with the GPL license).
