Method Details

### __init__ (self, knots, beta=2, wrap=False, name=`'````'`) (Constructor) |
New HeightIDWcosineLaw interpolator. Arguments: `knots` - The points with known height (`LatLon`s). `beta` - Inverse distance power (`int` 1, 2, or 3). `wrap` - Wrap and unrollPI longitudes (`bool`). `name` - Optional name for this height interpolator (`str`). Raises: `HeightError` - Insufficient number of `knots` or an invalid `knot` or `beta`. Overrides: object.__init__

### __call__ (self, *llis) (Call operator) |
Interpolate the height for one or several locations. Arguments: `llis` - The location or locations (`LatLon`, ... or `LatLon`s). Returns: A single interpolated height (`float`) or a list or tuple of interpolated heights (`float`s). Raises: `HeightError` - Insufficient number of `llis`, an invalid `lli` or an fidw issue. Overrides: _HeightBase.__call__

### height (self, lats, lons) |
Interpolate the height for one or several lat-/longitudes. Arguments: `lats` - Latitude or latitudes (`degrees` or `degrees`s). `lons` - Longitude or longitudes (`degrees` or `degrees`s). Returns: A single interpolated height (`float`) or a list of interpolated heights (`float`s). Raises: `HeightError` - Insufficient or non-matching number of `lats` and `lons` or an fidw issue. Overrides: _HeightIDW.height
