**geographic****coordinate system**(GCS) uses a three-dimensional spherical surface to define locations on the earth. A GCS is often incorrectly called a datum, but a datum is only one part of a GCS. A GCS includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid ). A point is referenced by its longitude and latitude ...- Examples

**coordinate**systems are the following: 1. The Cartesian**coordinate system**(also called the "rectangular**coordinate system**"), which, for three-dimensional flat space, uses three numbers representing distances. The three numbers represent first: the East or West direction, second: the North or South direction, and third: the Elevation. 2. Curvilin...A geographic coordinate system (GCS)
