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).
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.
Geodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid . They include geodetic latitude (north/south) ϕ, longitude (east/west) λ, and ellipsoidal height h (also known as geodetic height [1] ).
Jul 1, 2022 · A Geographic Coordinate System is a reference framework used to define the location of features on the surface of the Earth. It is a system of latitude and longitude coordinates that defines a three-dimensional position of a point on the Earth’s surface.
Geographic coordinate systems are spherical models of the earth. They are curved surfaces measured in divisions of latitude and longitude with typically units of degrees (decimal degrees or degrees minutes seconds which divide a full circle into 360 parts).

Oct 5, 2018 · A geographic coordinate system (GCS) defines locations on the earth using a three-dimensional spherical surface [1], it is a reference system that uses latitude and longitude to identify locations on a spheroid or sphere. A datum, prime meridian, and angular unit are parts of a GCS [2] .
