A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on the 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.

large version Archived. 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.
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 · Coordinate systems are frameworks that are used to define unique positions. For instance, in geometry, we use x (horizontal) and y (vertical) coordinates to define points on a two-dimensional plane. The coordinate system used to define locations on the three-dimensional earth is the geographic coordinate system (GCS), based on a sphere or spheroid.
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. The latitude and longitude coordinates are measured in degrees, minutes, and seconds, with the equator as the reference line for latitude and the Prime Meridian (Greenwich Meridian) as the ...
The geographic coordinate system is designed specifically to define positions on the Earth's roughly-spherical surface. Instead of the two linear measurement scales x and y, the geographic coordinate systems juxtaposes two curved measurement scales.
