Curvilinear orthogonal coordinate system
- Geodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid. They include geodetic latitude (north/south) ϕ, longitude (east/west) λ, and ellipsoidal height h (also known as geodetic height).

When we create datums, the reference ellipsoid an ellipsoid that is drawn to best-fit an area. World reference ellipsoids are drawn to best-fit the entire geoid; local ellipsoids are best fit on one side to a single place of the geoid is the half of the equation that decides the extent of the datum.
Mar 10, 2024 · The Global Positioning System uses the World Geodetic System (WGS84) as its reference coordinate system. It consists of a reference ellipsoid, a standard coordinate system, altitude data, and a geoid.
Reference systems can be based on the geoid, ellipsoid, or a plane. The physical earth’s gravity force can be modeled to create a positioning reference frame that rotates with the earth. The geoid is such a surface (an equipotential surface of the earth’s gravity field) that best approximates Mean Sea Level (MSL).
Dec 7, 2023 · A geodetic datum or reference frame is an abstract coordinate system with a reference surface (such as sea level) that serves to provide known locations to begin surveys and create maps.
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame) is a global datum reference or reference frame for precisely representing the position of locations on Earth or other planetary bodies by means of geodetic coordinates.
