Method Summary

static double	getGeodesicDistance(GeoLocation location, GeoLocation destination) Calculate geodesic distance in Meters between this Object and a second Object passed to this method using Thaddeus Vincenty's inverse formula See T Vincenty, "Direct and Inverse Solutions of Geodesics on the Ellipsoid with application of nested equations", Survey Review, vol XXII no 176, 1975.
static double	getGeodesicFinalBearing(GeoLocation location, GeoLocation destination) Calculate the final geodesic bearing between this Object and a second Object passed to this method using Thaddeus Vincenty's inverse formula See T Vincenty, "Direct and Inverse Solutions of Geodesics on the Ellipsoid with application of nested equations", Survey Review, vol XXII no 176, 1975.
static double	getGeodesicInitialBearing(GeoLocation location, GeoLocation destination) Calculate the initial geodesic bearing between this Object and a second Object passed to this method using Thaddeus Vincenty's inverse formula See T Vincenty, "Direct and Inverse Solutions of Geodesics on the Ellipsoid with application of nested equations", Survey Review, vol XXII no 176, 1975.
static double	getRhumbLineBearing(GeoLocation location, GeoLocation destination) Returns the rhumb line bearing from the current location to the GeoLocation passed in.
static double	getRhumbLineDistance(GeoLocation location, GeoLocation destination) Returns the rhumb line distance from the current location to the GeoLocation passed in.
