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 ). The triad is also known as Earth ellipsoidal … See more Longitude measures the rotational angle between the zero meridian and the measured point.

WebFeb 27, 2024 · A geographic coordinate system (GCS) is used to define locations on a model of the surface of the earth. The GCS uses a network of imaginary lines (longitude and latitude) to define locations. This network is called a graticule. So why isn’t knowing the latitude and longitude of a location good enough to know where it is?
