The GRASS GIS Homepage
The Geographic Resources Analysis Support System (GRASS) Geographic Information System (GIS) Homepage provides software used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. GRASS allows users to analyze, store, update, model, and display data quickly and easily. Although it was originally developed for use in land planning, its capabilities have been expanded and used in the fields of engineering, hydrology, geology, physics, statistics, remote sensing, and business.
