**geographic****coordinate****system**(GCS) is a**coordinate****system**associated with positions on Earth (**geographic**position). A GCS can give positions: as spherical**coordinate****system**using latitude, longitude, and elevation; as map**coordinates**projected onto the plane, possibly including elevation;A geographical

**coordinate****system**is a**coordinate****system**.This means that every place can be specified by a set of three numbers, called**coordinates**. A full circle can be divided into 360 degrees (or 360°); this was first done by the Babylonians; Ancient Greeks, like Ptolemy later extended the theory.Another common

**coordinate****system**for the plane is the polar**coordinate****system**. A point is chosen as the pole and a ray from this point is taken as the polar axis.For a given angle θ, there is a single line through the pole whose angle with the polar axis is θ (measured counterclockwise from the axis to the line).Pages in category "
