Coordinate System

Coordinate Systems define the exact location of a point on a spherical or planar surface. A geographic coordinate

system is a three-dimensional reference system that locates points on the Earth's surface using latitude and

locations are transformed from a three-dimensional space onto a two-dimensional surface. This is known as

projection. For more information on coordinate systems click here.
