Distances between
Three Locations
Enter the Latitudes and Longitudes of the three points in degrees, minutes and seconds of arc.
This calculation uses the ellipsoid of the Earth(flattened by 1 in 298 with an equatorial radius of 6378.14 km.

Location from Distance
and Bearing
Enter the Latitude and Longitude of the starting point, the distance (km) and bearing (degrees E of North) to another point.
This calculation uses spherical trigonometry but with the local radius
of curvature of the Earth as determined by the ellipsoid of the Earth at the
starting location. This calculation is OK for distances of 100's but not 1000's
of kilometres.
