                              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__

Property Details

### RAorder Get this rhumb line's Rhumb Area order (`int`, 4, 5, 6, 7 or 8). 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.
