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 geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth. A GCS is often incorrectly called a datum, but a datum is only one part of a GCS. A GCS includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid ).

Latitude and Longitude are the units that represent the coordinates at geographic coordinate system. To make a search, use the name of a place, city, state, or address, or click the location on the map to find lat long coordinates.
Jul 1, 2022 · 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.
May 21, 2023 · The essential cartographic considerations are map scale, coordinate systems, and map projections. Map scale is concerned with reducing geographical features of interest to manageable proportions. Coordinate systems help us define the positions of features on the earth’s surface.
Mar 10, 2024 · Latitude, Longitude, and Spherical Coordinate System Grids. When you put two coordinates together as a pair (X, Y), you can locate anything on Earth. Latitude and longitude form our coordinate system grid. Also, you can express coordinates in different ways. For example, you can use decimal degrees or degrees-minutes-seconds.
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.
