 The WGS 84 coordinate system also uses a geographic coordinate system, which is based on the latitude and longitude of a point on the Earth's surface. Latitude is the angle between a point on the Earth's surface and the equatorial plane, and is measured in degrees north or south of the equator. Longitude is the angle between a point on the Earth's surface and the Prime Meridian, and is measured in degrees east or west of the Prime Meridian.
