                                       RhumbSolve

Wrapper to invoke Karney's RhumbSolve, the Exact version of class pygeodesy.Rhumb.


Notes:
Instance Methods
 
Direct3(self, lat1, lon1, azi1, s12)
Return the destination lat, lon and reverse azimuth (final bearing) in degrees.
 
Inverse3(self, lat1, lon1, lat2, lon2)
Return the distance in meter and the forward and reverse azimuths (initial and final bearing) in degrees.
 
Line(self, lat1, lon1, azi1, caps=32640)
Set up an RhumbLineSolve to compute several points on a single rhumb line.

Method Details

Direct3 (self, lat1, lon1, azi1, s12)

 

Return the destination lat, lon and reverse azimuth (final bearing) in degrees.

Returns:
Destination3Tuple(lat, lon, final).

Inverse3 (self, lat1, lon1, lat2, lon2)

 

Return the distance in meter and the forward and reverse azimuths (initial and final bearing) in degrees.

Returns:
Distance3Tuple(distance, initial, final).

Line (self, lat1, lon1, azi1, caps=32640)

 

Set up an RhumbLineSolve to compute several points on a single rhumb line.

Arguments:
  • lat1 - Latitude of the first point (degrees).
  • lon1 - Longitude of the first point (degrees).
  • azi1 - Azimuth at the first point (compass degrees).
  • caps - Bit-or'ed combination of Caps values specifying the capabilities the RhumbLineSolve instance should possess, always Caps.ALL.
Returns:
A RhumbLineSolve instance.

Note: If the point is at a pole, the azimuth is defined by keeping lon1 fixed, writing lat1 = ±(90 − ε), and taking the limit ε → 0+.
