datum

The datum includes both a reference system (a mathematical assumption regarding the shape of the earth, or spheroid), such as the WGS 84, and a projection (usually UTM for low and middle latitudes, and Lambert for very high (polar) latitudes); the military grid reference system is based on the WGS 84 reference system and the UTM projection.
