@Alias({"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 its geoid expansion.
Radius: 6378137.0 m
Flattening: 1 / 298.257223563
