They can be classified into two broad categories: geographic coordinate systems and projected coordinate systems. A geographic coordinate system represents the Earth using a three-dimensional 3D spherical surface. Locations on Earth are represented by coordinates latitude and longitude. In contrast to a geographic coordinate system, a projected coordinate system is based on a map projection.

Because there is no perfect way to convert a curved surface to a flat surface, there are many projected coordinate systems available. Depending on the type of map projection used, different spatial properties will be distorted. Some of these properties include distance, area, shape, and direction.

An equal area projection is designed to maintain the area of specific features. In order to do this, these projections distort shape, angle, and scale. The Albers Equal Area Conic projection is an example of this type of map projection. Conformal projections maintain the shape of a small area. However, this means that the size of features is distorted. An equidistant projection maintains the scene along one or more lines. The distance between the center of the map and any other point is correct in an equidistant projection.

This type of projection is useful for point-to-point communication telecommunication applications. Azimuthal projections plots preserve the direction from one point to all others. Azimuthal projections can be combined with equal area, conformal, and equidistant projections. Some common azimuthal projections include gnomonic, stereographic, and orthographic projections. It is formatted in a specific way to convey information related to a particular coordinate system. After this statement, there are more sub-clauses that define various aspects of the projection.
