@jhamman it would be great if you could put together a PR for isel_points. The main complexity is that you'll want to write a version that also works with dask arrays. Let me know if that part is confusing, I can certainly help with that.

As for sel_points, we only need a kdtree if the underlying coordinates are 2D. If latitude and longitude (for example) are 1d, we can just use the existing machinery for remapping label based indexers to integers. This should be pretty straightforward, following the example of isel: https://github.com/xray/xray/blob/v0.5.1/xray/core/dataset.py#L1024 https://github.com/xray/xray/blob/v0.5.1/xray/core/indexing.py#L157
