wradlib.comp.togrid

wradlib.comp.togrid(src, trg, radius, center, data, interpol, *args, **kwargs)

Interpolate data from a radar location to the composite grid or set of locations

Parameters
  • src (numpy.ndarray) – array of float of shape (numpoints, ndim), cartesian x / y coordinates of the radar bins

  • trg (numpy.ndarray) – array of float of shape (numpoints, ndim), cartesian x / y coordinates of the composite

  • radius (float) – the radius of the radar circle (same units as src and trg)

  • center (numpy.ndarray) – array of float, the location coordinates of the radar

  • data (numpy.ndarray) – array of float, the data that should be transferred to composite

  • interpol (object) – an interpolation class name from wradlib.ipol e.g. Nearest or Idw

Other Parameters

*args (arguments of Interpolator (see class documentation))

Keyword Arguments

**kwargs (keyword arguments of Interpolator (see class documentation)) –

Returns

output (numpy.ndarray) – array of float, data of the radar circle which is interpolated on the composite grid

Note

Keyword arguments to be used while calling the interpolator can be issued as call_kwargs, eg. togrid(…, call_kwargs=dict(maxdist=10))
