Coordinate systems use one or more numbers, or coordinates, to uniquely determine the position of a point or geometry in space.

Coordinate systems use one or more numbers, or coordinates, to uniquely determine the position of a point or geometry in space.

Latitude and longitude is part of a common coordinate system to refer to points relative to the Earth's surface. Global Positioning System (GPS) uses a coordinate system with latitude and longitude for navigation and locating objects on or near the Earth.

A Cartesian coordinate system uses X-Y-Z values to represent points in a 3-D space.
