xarray.Dataset.xoak.sel

Dataset.xoak.sel(indexers=None, **indexers_kwargs)

Selection based on a ball tree index.

The index must have been already built using xoak.set_index().

It behaves mostly like xarray.Dataset.sel() and xarray.DataArray.sel() methods, with some limitations:

• Orthogonal indexing is not supported

• For vectorized (point-wise) indexing, you need to supply xarray objects

• Use it for nearest neighbor lookup only (it implicitly assumes method=”nearest”)

This triggers dask.compute() if the given indexers and/or the index coordinates are chunked.
