Method Details

__init__ (self, point1s, **fraction_name__datum_scaled_wrap)
(Constructor)

 

New FrechetFlatLocal/FrechetHubeny calculator/interpolator.

Arguments:
  • fraction_name__datum_scaled_wrap - Optional fraction=None and name=NN and keyword arguments for function pygeodesy.flatLocal.
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.

Note: The distance units are radians squared, not radians.

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:
Overrides: Frechet.discrete

distance (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:
Overrides: Frechet.distance
