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
