Earth ellipsoid

An Earth ellipsoid or Earth spheroid is a mathematical figure approximating the Earth's shape and size, used as part of a reference frame for coordinates and computations in geodesy, astronomy, and the geosciences. Various different reference ellipsoids have been used as approximations.
