Geodetic coordinate systems
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. By convention for the Earth, Moon and Sun, it is expressed in degrees ranging from −180° to +180°. For other bodies a … See more Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane … See more • Local geodetic coordinates • Geodetic datum • Geodesics on an ellipsoid See more Given geodetic coordinates, one can compute the geocentric Cartesian coordinates of the point as follows: where a and b are … See more WebA geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth.
