                              GeodesicLineExact

A pure Python version of Karney's C++ class GeodesicLineExact, modeled after Karney's Python class geodesicline.GeodesicLine.

Method Details

init (self, geodesic, lat1, lon1, azi1, caps=1929, **name)
(Constructor)

New GeodesicLineExact instance, allowing points to be found along a geodesic starting at (lat1, lon1) with azimuth azi1.

Arguments:

geodesic - The geodesic to use (GeodesicExact).
lat1 - Latitude of the first point (degrees).
lon1 - Longitude of the first point (degrees).
azi1 - Azimuth at the first points (compass degrees).
caps - Bit-or'ed combination of Caps values specifying the capabilities the GeodesicLineExact instance should possess, i.e., which quantities can be returned by calls to GeodesicLineExact.Position and GeodesicLineExact.ArcPosition.
name - Optional name=NN (str).

Raises:

TypeError - Invalid geodesic.

Overrides: object.__init__
