Method Details

### __init__ (self, points, datum=None, wrap=False, fraction=None, name='') (Constructor) |
New FrechetKarney 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 unroll180 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`. `ImportError` - Package geographiclib missing. `TypeError` - Invalid `datum`. Overrides: object.__init__
