Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.

Calculates the distance between two points of the Earth specified geodesic (geographical) coordinates along the shortest path - the great circle (orthodrome). Calculates the initial and final course angles and azimuth at intermediate points between the two given.

This calculator calculates the distance from one point on the Earth to another point, going through the Earth, instead of going across the surface.
