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
andKDTree
, which support various distance metrics. - pys2index:
S2PointIndex
for efficient indexing of lat/lon point data, based ons2geometry
.
Xoak also provides a mechanism for easily adding and registering custom index adapters.
Xoak can be installed using conda (or mamba):
$ conda install xoak -c conda-forge
or pip:
$ python -m pip install xoak
Xoak's optional dependencies can be installed using conda:
$ conda install scikit-learn pys2index -c conda-forge
