Which option correctly expands GCS (Geographic Coordinate System)?

GCS stands for Geographic Coordinate System, which is the standard GIS term for a system that uses latitude and longitude on a defined datum to locate positions on the Earth’s surface. This name emphasizes the geographic, not the mathematical modeling alone, of coordinates. A Geodetic Coordinate System is related but refers more directly to the underlying datum and ellipsoid used to model the Earth's shape, rather than the geographic coordinates themselves. The other options aren’t the conventional expansions used in GIS terminology, so Geographic Coordinate System is the correct match. In practice, a GCS helps you work with coordinates like degrees of latitude and longitude tied to a datum such as WGS84 or NAD83.
