                          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 Details

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

New RhumbLine.

Arguments:

rhumb - The rhumb reference (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__

Property Details

RAorder

Get method:: RAorder(self) - Get this rhumb line's Rhumb Area order (int, 4, 5, 6, 7 or 8).
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.
