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.

Learn what a geographic coordinate system (GCS) is and how it defines locations on the earth using longitude and latitude angles. Find out how to measure and display data on a GCS and how it differs from a projection.
Mar 10, 2024 · Learn how to use latitude and longitude to locate any position on Earth with a geographic coordinate system. Find out the difference between degrees-minutes-seconds and decimal degrees, and the common coordinate reference systems such as WGS84 and NAD83.
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.
