                          RhumbLine

Compute one or several points on a single rhumb line.

Class RhumbLine facilitates the determination of points on a single rhumb line. The starting point (lat1, lon1) and the azimuth azi12 are specified once.

Method RhumbLine.Position returns the location of an other point at distance s12 along and the area S12 under the rhumb line.

Method RhumbLine.intersection2 finds the intersection between two rhumb lines.

Method RhumbLine.nearestOn4 computes the nearest point on and the distance to a rhumb line in different ways.

Method Details

__init__ (self, rhumb, lat1=0, lon1=0, azi12=None, **caps_name)
(Constructor)

 

New rhumbx.RhumbLine.

Arguments:
  • rhumb - The rhumb reference (rhumbx.Rhumb).
  • lat1 - Latitude of the start point (degrees90).
  • lon1 - Longitude of the start point (degrees180).
  • azi12 - Azimuth of this rhumb line (compass degrees).
  • caps_name - Optional keyword arguments name=NN and caps=0, a bit-or'ed combination of Caps values specifying the required capabilities. Include Caps.LINE_OFF if updates to the rhumb should not be reflected in this rhumb line.
Overrides: object.__init__
