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
KDTree, which support various distance metrics.
S2PointIndexfor efficient indexing of lat/lon point data, based on s2geometry.
Xoak also provides a mechanism for easily adding and registering custom index adapters.
