Reference ellipsoid for World Geodetic System of 1984

WebThe Earth is almost spherical, however there is a tiny bulge at the equator that makes it ~0.33% larger than at the poles. The ellipsoid is an approximation and does not fit the Earth perfectly. There are different ellipsoids in use, some are designed to fit the whole Earth (WGS84, GRS80) and some are designed to fit a local region (NAD27).
