Rhumb Line Calculator : Departure Point Destination Point; Latitude ° ' ° ' ...
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
Rhumb Line calculation: Inverse: lat1 lon1 lat2 lon2. → azi12 s12. Direct: lat1 lon1 azi12 s12. → lat2 lon2. Input (ex. « 40.6 -73.8 49°01'N 2°33'E » [inverse], « 40d38'23"N 073d46'44"W 53d30' 5850e3 » [direct]): . Output format: Decimal degrees. Degrees minutes seconds. Output precision:

Rhumb line, Great circle calculations. Choose your calculation: Rhumb line calculation: Departure position (latitude, longitude) + Course and Distance, to compute Arrival position.
Rhumb lines are lines of constant direction. Rhumb line track = average great circle track. If two points are on the same latitude, rhumb line track is equal to the great circle track at the midpoint. If two points are on the same latitude, the rhumb line track between them is either 090° or 270°.
To Calculate Departure when the course is Known: Dep = Dist x Sin(course) To Calculate Distance when departure and course are known: Dist = Dep ÷ Sin (course) To Calculate Dlat when the distance and course are known: DLat = Dist x Cos(course) To Calculate Course to Steer (the rhumb line course between two points)
