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.
Jul 1, 2022 · Examples of projected coordinate systems include Universal Transverse Mercator (UTM), State Plane Coordinate System (SPCS), and Lambert Conformal Conic. Geographic Coordinate System Units The units of measurement for degrees of longitude (x-coordinates) and degrees of latitude (y-coordinates) in geographic coordinate systems, often known as GCS ...
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.
Definition. A Geographic Coordinate System (GCS) is a type of coordinate system that enables every location on Earth to be specified by a set of numbers or letters. It is a system that uses latitude and longitude to define the positions of points on the surface of a sphere or an ellipsoid.
Latitude and longitude, coordinate system by means of which the position or location of any place on Earth’s surface can be determined and described. Latitude is a measurement of location north or south of the Equator. Longitude is a similar measurement east or west of the Greenwich meridian.

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.
Mar 8, 2024 · Glossary. What are Geographic Coordinate Systems? On Mar 8, 2024. Ever wonder how your phone magically knows where you are on the map? Well, it’s all thanks to the secret sauce called A Geographic Coordinate System. Geographic Coordinate Systems (GCS) are a set of rules and parameters used to locate points on the Earth’s surface.
