raster file - (aka, cell file in earlier releases of GRASS). The digital data file in which raster map data are stored in GRASS. Each data file describes a specific thematic map in terms of its geographic coordinates. Supporting files describe the category values, labels, map title, history, etc., corresponding to this raster data file. All of the files relating to a given raster data file are collectively termed a raster map layer.
