Xoak: Xarray extension for indexing irregular grids

Xoak is an Xarray extension that allows point-wise selection of irregular, n-dimensional data encoded in coordinates with an arbitrary number of dimensions.

It provides a built-in index adapter for Scipy’s cKDTree, as well as adapters for index structures implemented in these 3rd-party libraries (optional dependencies):

• Scikit-Learn: BallTree and KDTree, which support various distance metrics.

• pys2index: S2PointIndex for efficient indexing of lat/lon point data, based on s2geometry.

Xoak also provides a mechanism for easily adding and registering custom index adapters.
