The current nearest neighbour interpolation we have is the SciPy one and it's fairly limited. With a new dedicated gridder we can:

  1. Take advantage of pykdtree
  2. Support spherical coordinates with scikit-learn's BallTree (with haversine distance)
  3. Allow averaging k-nearest neighbours instead of just the 1
  4. Support weights in the averaging

The new class would sit in a verde/neighbours.py module.
