Geographic Coordinates system : Geographic coordinate system is a coordinate system that enables every location on the Earth to be specified by a set of numbers or letters. The coordinates are often chosen such that one of the numbers represents vertical position, and two or three of the numbers represent horizontal position. A common choice of coordinates is latitude, longitude and elevation.

Latitude indicates the location of a place on Earth north or south of the Equator. Latitude is an angular measurement in degrees (marked with °) ranging from 0° at the Equator to 90° at the poles (90° N for the North Pole or 90° S for the South Pole).

Longitude is an imaginary line that runs from the North Pole to the South Pole and is used to describe the location of a place on Earth east or west of the zero or prime meridian. In 1884, the International Meridian Conference adopted the Greenwich Meridian as the universal prime meridian or zero point of longitude. Longitude is measured in degrees ranging from 0° at the Prime Meridian to +180° eastward and -180° westward. Each degree of longitude is further sub-divided into 60 minutes, each of which is further sub-divided into 60 seconds.

Equator: Located at zero degrees latitude (North or South,) is 24,901.55 miles long and divides the Planet Earth into the Northern and Southern Hemispheres.
