Method Details

__init__ (self, geodesic, lat1, lon1, azi1, caps=3968, 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 (str).
Raises:
  • TypeError - Invalid geodesic.
Overrides: object.__init__
