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](https://docs.scipy.org/doc/scipy/reference/)’s cKDTree, as well as adapters for index structures implemented in these 3rd-party libraries (optional dependencies):

• [Scikit-Learn](https://scikit-learn.org): BallTree and KDTree, which support various distance metrics.

• [pys2index](https://github.com/benbovy/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.

## Install

Xoak can be installed using conda (or mamba):

`bash $ conda install xoak -c conda-forge `

or pip:

`bash $ python -m pip install xoak `

Xoak’s optional dependencies can be installed using conda:

`bash $ conda install scikit-learn pys2index -c conda-forge `
