Coordinate Reference Systems

A Coordinate Reference System is a method of projecting positions in the world onto screen/paper.

The surface of the Earth is curved, but paper is flat. These two facts mean that paper maps will always be slightly distorted.

Different coordinate reference systems are designed to minimise the distortion in different ways. Some coordinate reference systems show orientation accurately, some show areas accurately etc.

The following is a list of the available Coordinate Reference System types.
