Method Details

__init__ (self, points, fraction=None, name='', units='', **wrap_adjust)
(Constructor)

 

New Frechet... calculator/interpolator.

Arguments:
  • points - First set of points (LatLon[], Numpy2LatLon[], Tuple2LatLon[] or other[]).
  • fraction - Index fraction (float in EPS..EPS1) to interpolate intermediate points or use None, 0 or 1 for no intermediate points and no fractional indices.
  • name - Optional calculator/interpolator name (str).
  • units - Optional, the distance units (Unit or str).
  • wrap_adjust - Optionally, wrap and unroll longitudes, iff applicable (bool) and adjust wrapped, unrolled longitudinal delta by the cosine of the mean latitude, iff applicable.
Raises:
  • FrechetError - Insufficient number of points or invalid fraction or {wrap} or ajust not applicable.
Overrides: object.__init__

discrete (self, points, fraction=None)

 

Compute the forward, discrete Fréchet distance.

Arguments:
  • points - Second set of points (LatLon[], Numpy2LatLon[], Tuple2LatLon[] or other[]).
  • fraction - Index fraction (float in EPS..EPS1) to interpolate intermediate points or use None, 0 or 1 for no intermediate points and no fractional indices.
Returns:
A Frechet6Tuple(fd, fi1, fi2, r, n, units).
Raises:
Overrides: Frechet.discrete
