Geographic coordinate system

A geographic coordinate system (GCS) is a coordinate system associated with positions on Earth (geographic position). A GCS can give positions: * as spherical coordinate system using latitude, longitude, and elevation; * as map coordinates projected onto the plane, possibly including elevation; * as earth-centered, earth-fixed (ECEF) Cartesian coordinates in 3-space; * as a set of numbers, letters or symbols forming a geocode.
