Method Details

### __init__ (self, points, datum=None, wrap=False, fraction=None, name='') (Constructor) |
New FrechetCosineAndoyerLambert calculator/interpolator. Arguments: `points` - First set of points (`LatLon`[], Numpy2LatLon[], Tuple2LatLon[] or `other`[]). `datum` - Optional datum overriding the default `Datums.WGS84` and first `points`' datum (Datum). `wrap` - Wrap and unrollPI longitudes (`bool`) `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`). Raises: `FrechetError` - Insufficient number of `points` or invalid `fraction`. `TypeError` - Invalid `datum`. 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: `FrechetError` - Insufficient number of `points` or an invalid `point` or `fraction`. `RecursionError` - Recursion depth exceeded, see sys.getrecursionlimit(). Overrides: Frechet.discrete

### distance (self, p1, p2) |
Return the cosineAndoyerLambert_ distance in `radians`. Overrides: Frechet.distance
