public final class Ellipsoid
extends Object
implements Serializable

Represents an earth ellipsoid, which is a mathematical figure approximating the shape of the Earth, used as a reference frame for computations in geodesy, astronomy and the geosciences. Various different ellipsoids have been used as approximations.
