Method Details

__call__ (self, *llis)
(Call operator)

 

Interpolate the height for one or several locations.

Arguments:
  • llis - The location or locations (LatLon, ... or LatLons).
Returns:
A single interpolated height (float) or a list or tuple of interpolated heights (floats).
Raises:
  • HeightError - Insufficient number of llis, an invalid lli or an fidw issue.
Overrides: _HeightBase.__call__

__init__ (self, knots, beta=2, wrap=False, name='')
(Constructor)

 

New HeightIDWhaversine interpolator.

Arguments:
  • knots - The points with known height (LatLons).
  • 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 knot or beta.
Overrides: object.__init__

height (self, lats, lons)

 

Interpolate the height for one or several lat-/longitudes.

Arguments:
  • lats - Latitude or latitudes (degrees or degreess).
  • lons - Longitude or longitudes (degrees or degreess).
Returns:
A single interpolated height (float) or a list of interpolated heights (floats).
Raises:
  • HeightError - Insufficient or non-matching number of lats and lons or an fidw issue.
Overrides: _HeightIDW.height
