Method Details

### __init__ (self, knots, name='', **wrap) (Constructor) |
New HeightLinear interpolator. Arguments: `knots` - The points with known height (`LatLon`s). `name` - Optional name for this height interpolator (`str`). `wrap` - If `True`, wrap or normalize all `knots` and `llis` locations (`bool`). Raises: `HeightError` - Insufficient number of `knots` or invalid `knot`. `ImportError` - Package `numpy` or `scipy` not found or not installed. `SciPyError` - A `scipy.interpolate.interp2d` issue. `SciPyWarning` - A `scipy.interpolate.interp2d` warning as exception. Overrides: object.__init__ See Also: HeightCubic.__init__ for details about `knots`, `name`, `wrap` and other exceptions.

### __call__ (self, *llis, **wrap) (Call operator) |
Interpolate the height for one or several locations. Arguments: `llis` - One or more locations (`LatLon`s), all positional. `wrap` - If `True`, wrap or normalize all `llis` locations (`bool`), overriding the `knots` setting. Returns: A single interpolated height (`float`) or a list or tuple of interpolated heights (`float`s). Raises: `SciPyError` - A `scipy.interpolate.interp2d` issue. `SciPyWarning` - A `scipy.interpolate.interp2d` warning as exception. Overrides: _HeightsBase.__call__ See Also: _HeightsBase.__call__ for details about `llis`, `wrap`, return values and other exceptions.

### height (self, lats, lons, **wrap) |
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). `wrap` - If `True`, wrap or normalize all `lats` and `lons` locationts (`bool`), overriding the `knots` setting. Returns: A single interpolated height (`float`) or a list of interpolated heights (`float`s). Raises: `SciPyError` - A `scipy.interpolate.interp2d` issue. `SciPyWarning` - A `scipy.interpolate.interp2d` warning as exception. Overrides: _HeightsBase.height See Also: _HeightsBase.height for details about `lats`, `lons`, `wrap`, return values and other exceptions.
