Examples of global datums include World Geodetic System (WGS 84, also known as EPSG:4326), the default datum used for the Global Positioning System, and the International Terrestrial Reference System and Frame (ITRF), used for estimating continental drift and crustal deformation.
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.
Jul 1, 2022 · Learn about the types, units, and examples of geographic coordinate systems, such as latitude and longitude, UTM, and SPCS. Find out how to convert from one coordinate system to another using datums and map projections.
Learn what a geographic coordinate system (GCS) is and how it uses longitude and latitude to locate points on the earth. Find out how GCS differs from a projection and how to use it in ArcMap.
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.
Learn how geographic coordinate systems use latitude and longitude to describe point locations on earth. See examples of spherical models, graticules, and projections of the earth's surface.
