Vincenty solutions of geodesics on the ellipsoid in JavaScript | Movable Type ScriptsDistances and bearings between points on an ellipsoidal-model earth For the benefit of the terminally obsessive (as well as the genuinely needy, of course), Thaddeus Vincenty devised formulæ for calculating geodesic distances between a pair of latitude/longitude points on the earth’s surface, using an accurate ellipsoidal model of the earth. When I looked up the references (‘Direct and Inverse
