nsrdb.utilities.interpolation.nn

nn(data, indices, distance=None, dist_thresh=None)[source]

Nearest Neighbor Spatial Interpolation.

Parameters:

  • data (np.array) – Coarse resolution NSRDB data to be interpolated. Must be for a single timestep and be flattened/raveled.

  • indices (np.ndarray) – Index array generated by a sklearn Tree query.

  • distance (np.ndarray) – Optional distance array generated by a sklearn Tree query for distance filtering.

  • dist_thresh (int | float) – Distance threshold. Neighbors with distance greater than this value are not interpolated.

Returns:

out (np.array) – Fine resolution NSRDB data that has been interpolated.
