Commonly referred to as GRASS, this is free Geographic Information System
(GIS) software 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. GRASS is an official project of
the Open Source Geospatial Foundation.
Creates a composite raster map layer by using known category values from one (or more) map layer(s) to fill in areas of "no data" in another map layer.
