Method Details

### __init__(self, points, datum=None, wrap=False, seed=None, name=`'````'`) (Constructor) |
New HausdorffKarney calculator. Parameters: `points` - Initial set of points, aka the `model` or `template` (`LatLon`[], `Numpy2LatLon`[], `Tuple2LatLon`[] or `other`[]). `datum` - Optional datum (Datum to use, overriding the default `model points[0].datum`. `wrap` - Wrap and unroll180 longitudes (`bool`). `seed` - Random sampling seed (`any`) or `None`, `0` or `False` for no random sampling. `name` - Optional calculator name (`str`). Raises: `HausdorffError` - Insufficient number of `points` or invalid `seed`. `ImportError` - Package GeographicLib missing. `TypeError` - Invalid `datum`. Overrides: object.__init__

### distance(self, p1, p2) |
Return the non-negative angular distance in `degrees`. Overrides: Hausdorff.distance

### directed(self, points, early=True) |
Compute only the `forward Hausdorff` distance. Parameters: `points` - Second set of points, aka the `target` (`LatLon`[], `Numpy2LatLon`[], `Tuple2LatLon`[] or `other`[]). `early` - Enable or disable early breaking (`bool`). Returns: A Hausdorff6Tuple`(hd, i, j, mn, md, units)`. Raises: `HausdorffError` - Insufficient number of `points`. Overrides: Hausdorff.directed

### symmetric(self, points, early=True) |
Compute the combined `forward and reverse Hausdorff` distance. Parameters: `points` - Second set of points, aka the `target` (`LatLon`[], `Numpy2LatLon`[], `Tuple2LatLon`[] or `other`[]). `early` - Enable or disable early breaking (`bool`). Returns: A Hausdorff6Tuple`(hd, i, j, mn, md, units)`. Raises: `HausdorffError` - Insufficient number of `points`. Overrides: Hausdorff.symmetric

Property Details

### datum Get method: datum(self) - Get the datum of this calculator (Datum). Set method: immutable(inst, value) - Throws an `AttributeError`, always.
