Measure the distance between two coordinates exactly on the WGS84 ellipsoid and with haversine, with bearings, rhumb line, midpoint and the route on a map.
Enter two points in almost any notation – decimal degrees, degrees-minutes-seconds, a geo: URI or a Google Maps / OpenStreetMap link – or click them on the map and drag the markers. The distance is computed on the WGS84 ellipsoid with Karney's geodesic algorithms, next to the classic haversine estimate and how far it is off.
You also get the initial and final bearing, the constant-course rhumb line, the midpoint, and the great-circle route drawn correctly even across the date line. Kilometres, miles or nautical miles.
