Calculate the rhumb line distance and bearing between two points on a spherical surface. Enter the departure and destination coordinates and get the results in nautical miles and degrees.
Calculate the course angle and the distance between two points on a loxodrome (rhumb line) using geographical coordinates. A loxodrome is a line that crosses all meridians at the same angle and is used for navigation on Mercator maps.
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.
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.
In navigation, a rhumb line, rhumb (/ r ʌ m /), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true north.
The first calculates a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with given geographical coordinates. The second one outputs compass point given course angle in degrees.
