All Implemented Interfaces:

EarthModel

@Alias(value={"wgs84","WGS-84","WGS84"})
public class WGS84SpheroidEarthModel
extends AbstractEarthModel

The WGS84 spheroid earth model, without height model (so not a geoid, just a spheroid!) Note that EGM96 uses the same spheroid, but what really makes the difference is it's geoid expansion. Radius: 6378137.0 m Flattening: 1 / 298.257223563
