Coordinate system

Definition

A coordinate system is a reference system based on mathematical rules for specifying positions (locations) on the surface of the earth. The coordinate values can be spherical (latitude and longitude) using angular units of measure such as degrees, minutes and seconds or planar (Universal Transverse Mercator) using linear units such as metres. Cartographic boundary files, digital boundary files, representative points and the road network files are disseminated in Lambert coordinates.
