  1. [data models] A fundamental data structure consisting of a matrix of equally sized cells, or pixels, arranged in rows and columns, and composed of single or multiple bands. Each cell represents a location on the earth's surface and contains a numeric value that represents a particular attribute or phenomenon, such as temperature at a particular height or depth, elevation, or image brightness value. Groups of cells that share the same coordinate value represent the same geographic feature. Media/raster.gif
