Method Details

init (self, point1s, **fraction_name__adjust_radius_wrap)
(Constructor)

New FrechetEuclidean calculator/interpolator.

Arguments:

fraction_name__adjust_radius_wrap - Optional fraction=None and name=NN and keyword arguments for function pygeodesy.euclidean.

Raises:

FrechetError - Insufficient number of point1s or an invalid point1, fraction or units.

Overrides: object.__init__

See Also: Frechet.__init__ for details about point1s, fraction, name and other exceptions.

discrete (self, point2s, fraction=None)

Compute the forward, discrete Fréchet distance.

Arguments:

point2s - Second set of points (LatLon[], Numpy2LatLon[], Tuple2LatLon[] or other[]).
fraction - Index fraction (float in EPS..EPS1) to interpolate intermediate point2s or use None, 0 or 1 for no intermediate point2s and no fractional indices.

Returns:

A Frechet6Tuple

(fd, fi1, fi2, r, n, 
          units)

Raises:

FrechetError - Insufficient number of point2s or an invalid point2 or fraction.
RecursionError - Recursion depth exceeded, see sys.getrecursionlimit.

Overrides: Frechet.discrete
