Documentation
A datum specifies the relationship of a coordinate system to an object, thus creating a coordinate reference system. For geodetic and vertical coordinate reference systems the datum relates the coordinate system to the earth. With other types of coordinate reference system the datum may relate the coordinate system to another physical or virtual object. A datum uses a parameter or set of parameters that determine the location of the origin of the coordinate reference system. Each datum subtype can be associated with only specific types of coordinate reference systems.
