Un sistem de coordonate geografice definește orice locații de pe Pământ prin 2 sau 3 coordonate ale unui sistem de coordonate sferice care este aliniat la axa în jurul căreia se învârte Pământul. Pornind de la teoriile vechilor babilonieni, extinse ulterior de Ptolemeu, unui cerc întreg i s-au atribuit 360°.
Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems . In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1] A geographic coordinate transformation is a ...

The World Geodetic System ( WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
The geographic coordinate system enables any place in the world to be located using its latitude and longitude. The latitude is the position relative to the equator, specifying the north-south position. The longitude specifies the east-west position measured from a reference meridian (usually the Greenwich Prime Meridian).
