pygeodesy.karney.Rhumb8Tuple

Class Rhumb8Tuple

8-Tuple (lat1, lon1, lat2, lon2, azi12, s12, S12, a12) with lat- lat1, lat2 and longitudes lon1, lon2 of both points, the azimuth of the rhumb line azi12, the distance s12, the area S12 under the rhumb line and the angular distance a12 between both points.

Instance Methods

toDirect9Tuple(self, dflt=nan, **a12_azi1_azi2_m12_M12_M21)
Convert this Rhumb8Tuple result to a 9-tuple, like Karney's method geographiclib.geodesic.Geodesic._GenDirect.
