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]
Figure 2.11.1 The geographic coordinate system. Credit: David DiBiase. Longitude specifies positions east and west as the angle between the prime meridian and a second meridian that intersects the point of interest. Longitude ranges from +180 (or 180° E) to -180° (or 180° W). 180° East and West longitude together form the International Date ...
Mar 10, 2024 · A geographic coordinate system defines two-dimensional coordinates based on the Earth’s surface. It has an angular unit of measure, prime meridian, and datum (which contains the spheroid). As shown in the image below, lines of longitude have X-coordinates between -180 and +180 degrees. Longitude Coordinates.
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.
Jul 1, 2022 · Caitlin Dempsey. Updated: July 1, 2022. Maps and Cartography. Map projections allow us to convert from sphere to planar (flat) representation. Geographic coordinate systems allow for the measurements of distances and to determine direction. Except for the Geographic Grid all coordinate systems are based on some form of map projection.
