Class WGS84SpheroidEarthModel

java.lang.Object

de.lmu.ifi.dbs.elki.math.geodesy.AbstractEarthModel

de.lmu.ifi.dbs.elki.math.geodesy.WGS84SpheroidEarthModel

All Implemented Interfaces:

EarthModel

@Alias(value={"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

Since:

0.6.0
