Method Details

__init__ (self, point1s, fraction=None, name='', units='', **kwds)
(Constructor)

 

New Frechet... calculator/interpolator.

Arguments:
  • point1s - First set of points (LatLon[], Numpy2LatLon[], Tuple2LatLon[] or other[]).
  • fraction - Index fraction (float in EPS..EPS1) to interpolate intermediate point1s or use None, 0 or 1 for no intermediate point1s and no fractional indices.
  • name - Optional calculator/interpolator name (str).
  • units - Optional distance units (Unit or str).
  • kwds - Optional keyword argument for distance function, retrievable with property kwds.
Raises:
  • FrechetError - Insufficient number of point1s or an invalid point1, fraction or units.
Overrides: object.__init__

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, point1, point2, *args, **kwds)

 

Must be overloaded.

Overrides: Frechet.distance
