Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. Originally written by the U.S. Army Construction Engineering Research Laboratories (USA-CERL) branch of the US Army Corp of Engineers as a tool for land management and environmental planning by the military, GRASS has evolved into a powerful utility with a wide range of applications in many different areas of scientific research. GRASS is currently used in academic and commercial settings around the world, as well as many governmental agencies including NASA, NOAA, USDA, the National Park Service, the U.S. Census Bureau, USGS, and many environmental consulting companies.
