Method Details

__init__ (self, knots, beta=2, name='', **distanceTo_kwds)
(Constructor)

 

New HeightIDWdistanceTo interpolator.

Arguments:
  • knots - The points with known height (LatLons).
  • beta - Inverse distance power (int 1, 2, or 3).
  • name - Optional name for this height interpolator (str).
  • distanceTo_kwds - Optional keyword arguments for the points' LatLon.distanceTo method.
Raises:
Overrides: object.__init__

Note: All points must be instances of the same ellipsoidal or spherical LatLon class, not checked however.

__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:
Overrides: _HeightBase.__call__

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:
Overrides: _HeightIDW.height
