                                           double longitude,
                                           double latitude)

Get the point vector in this earth-center coordinate for a given longitude [deg] and latitude [deg].

        double height :  height [cm] from the earth center
        double longitude : longitude [deg]
        double latitude :  latitude [deg]
        

Returns J3Vector defined in the EarthCenterCoordinate

getSurfacePoint

public J3Vector getSurfacePoint(double longitude,
                       double latitude)
