wradlib.ipol.map_coordinates

wradlib.ipol.map_coordinates(cartgrid, values, newgrid, **kwargs)

Map array values defined by cartesian coordinate array cartgrid to new coordinates defined by newgrid using spline interpolation.

Keyword arguments are fed through to scipy.ndimage.map_coordinates

Parameters:

• cartgrid (numpy.ndarray) – 3-dimensional array (nx, ny, lon/lat) of floats

• values (numpy.ndarray) – 2-dimensional array (nx, ny) of data values

• newgrid (numpy.ndarray) – Nx2-dimensional array (…, lon/lat) of floats

• kwargs (scipy.ndimage.map_coordinates)

Returns:

interp (numpy.ndarray) – array with interpolated values of size N
