May 23, 2024 · What are the 4 components of a geographic coordinate system? A geographic coordinate system (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 values. Longitude and latitude are angles measured from the earth’s center to a point on the earth’s ...
