pygeodesy.rhumb

Package rhumb

Package of lazily imported rhumb modules rhumb.aux_, rhumb.ekx and rhumb.solve.

Note: S12 area calculations in classes RhumbAux and RhumbLineAux depend on class AuxDST which requires numpy to be installed, version 1.16 or newer.

Version: 25.12.06

Submodules

pygeodesy.rhumb.aux_: A pure Python version of Karney's Auxiliary Latitudes, C++ classes Rhumb and RhumbLine from GeographicLib version 2.2+ renamed to RhumbAux respectively RhumbLineAux.
pygeodesy.rhumb.bases: (INTERNAL) base classes RhumbBase and RhumbLineBase, pure Python version of Karney's C++ classes Rhumb and RhumbLine from GeographicLib versions 2.0 and 2.2 and Karney's C++ example Rhumb intersect.
pygeodesy.rhumb.ekx: A pure Python version of Karney's elliptic functions, Krüger series expansion, C++ classes Rhumb and and RhumbLine from GeographicLib version 2.0, kept for backward compatibility.
pygeodesy.rhumb.solve: Wrapper to invoke Karney's RhumbSolve utility as an (exact) rhumb or rhumb line from either GeographicLib 2.0 or 2.2+.

Classes

RhumbAux
Class to solve the direct and inverse rhumb problems, based on Auxiliary Latitudes for accuracy near the poles.

RhumbLineAux
Compute one or several points on a single rhumb line.

Rhumb
Class to solve the direct and inverse rhumb problems, based on elliptic functions or Krüger series expansion

RhumbLine
Compute one or several points on a single rhumb line.

RhumbSolve
Wrapper to invoke Karney's RhumbSolve like a class, similar to pygeodesy.Rhumb and pygeodesy.RhumbAux.

RhumbLineSolve
Wrapper to invoke Karney's RhumbSolve like a class, similar to pygeodesy.RhumbLine and pygeodesy.RhumbLineAux.

RhumbSolve7Tuple
7-Tuple (lat1, lon1, lat2, lon2, azi12, s12, S12) with lat- lat1, lat2 and longitudes lon1, lon2 of both points, the azimuth of the rhumb line azi12, the distance s12 and the area S12 under the rhumb line between both points.

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.
