Instance Methods

__init__(self, point1s, fraction=None, units='', **name__kwds)

distance(self, point1, point2, *args, **kwds)
Must be overloaded.

point(self, point)

Method Details

init (self, point1s, fraction=None, units='', **name__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.
units - Optional distance units (Unit or str).
name__kwds - Optional name=NN for this calculator/interpolator (str) and any keyword arguments for the 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:

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

Overrides: Frechet.discrete

distance (self, point1, point2, *args, **kwds)

Must be overloaded.

Overrides: Frechet.distance

point (self, point)

Return point as PhiLam2Tuple to maintain backward compatibility of FrechetRadians.

Arguments:

point - The point to convert ((LatLon, Numpy2LatLon, Tuple2LatLon or other).

Returns:

A PhiLam2Tuple(phi, lam).

Overrides: Frechet.point
