Method Detail

_calcLLFactor

public static final double _calcLLFactor(double lon1,
                                         double lat1,
                                         double lon2,
                                         double lat2)

All parameters are in radians.

distanceInKMByRadians

public static final double distanceInKMByRadians(double lon1,
                                                 double lat1,
                                                 double lon2,
                                                 double lat2)

The latitudes/longitudes are in radians.

Returns:

in kilo-meters

distanceInKMByRadians

public static final double distanceInKMByRadians(double[] a,
                                                 double[] b)

distanceInKMByDegrees

public static final double distanceInKMByDegrees(double lon1,
