A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] . 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.

A geographical coordinate system is a coordinate system. This means that every place can be specified by three sets of three numbers, called coordinates. A full circle can be divided into 360 degrees (or 360°); this was first done by the Babylonians; Ancient Greeks, like Ptolemy later extended the theory. Today, degrees are divided further.
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]
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).
May 21, 2023 · The coordinate system used to define locations on the three-dimensional earth is the geographic coordinate system (GCS), based on a sphere or spheroid. A spheroid (a.k.a. ellipsoid) is simply a slightly wider sphere than it is tall and approximates the actual shape of the earth more closely.
Jul 1, 2022 · A Geographic Coordinate System is a 3D reference system that uses latitude and longitude to define the location of a point on the Earth’s surface.
