It has an angular unit of measure, prime meridian, and datum (which. Geographic coordinate systems (gcs) and projected coordinate systems (pcs). A geographic coordinate system is a reference framework used to define the location of features on the surface of the earth.

A gcs is often incorrectly called a datum, but a datum is only one part. A geographic coordinate system (gcs) is a spherical or geodetic coordinate system for measuring and communicating positions directly on earth as latitude and longitude. Longitude ranges from +180 (or 180° e).
The most widely used global coordinate system consists of lines of geographic latitude (phi or f or j) and longitude (lambda or l).
Geographic coordinate systems (gcs) are a set of rules and parameters used to locate points on the earth’s surface. Longitude specifies positions east and west as the angle between the prime meridian and a second meridian that intersects the point of interest. Lines of equal latitude are called parallels. A point is referenced by its longitude and latitude values
What is a geographic coordinate system? These systems employ latitude coordinates and longitude.
