|Course angle and the distance between the two points on loxodrome (rhumb line).|
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
|Course angles and distance between the two points on the orthodrome(great circle)|
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.
|Distance through the Earth|
This calculator calculates the distance from one point on the Earth to another point, going through the Earth, instead of going across the surface.
