# GRASS Help System

raster data (raster format) - A data format whose basic unit is the grid cell. Data are stored on a grid containing rectangular cells of uniform size. Cell dimensions denote data resolution. Each cell within the grid can be assigned a data value. Smaller grid cell size therefore allows more data to be stored for a given geographic area (i.e., can present data at a larger scale). See vector data for comparison.
