A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others.

Un système de coordonnées géographiques inclut une unité de mesure angulaire, un premier méridien et un datum (basé sur un sphéroïde ). Un point est référencé par ses valeurs de longitude et de latitude. La longitude et la latitude sont les angles mesurés à partir du centre de la Terre vers un point à la surface de la Terre.
In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
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.
