WGS 84 is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS satellite navigation system (the Global Positioning System). Geographic coordinates (latitude and longitude) define a position on the Earth's surface. Coordinates are angular units.The canonical form of latitude and longitude representation uses degrees (Â°), minutes (â²), and seconds (â³). GPS systems widely use coordinates in degrees and decimal minutes, or in decimal degrees.eographic coordinates (latitude and longitude) define a position on the Earth's surface.
