I saw in the conversation that one of the problems was the serialization of this information in NetCDF files. My class allows you to serialize the tree:

```python
In [5]: coordinates = np.asarray(( 
                np.random.uniform(-180.0, 180.0, 4), 
                np.random.uniform(-90.0, 90.0, 4), 
                np.random.uniform(-10000, 100000, 4))).T 
In [6]: tree.packing(coordinates) 
In [7]:tree.__getstate__()

```
It can be structured in a NetCDF file. Thanks again for the information.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,448082431

It would be indeed really nice to add custom indexes to xarray like R*Tree! Unfortunately, this isn't supported right now, but it's one of the main points in xarray's [development roadmap](http://xarray.pydata.org/en/stable/roadmap.html#flexible-indexes).

@shoyer has started working on this in #2195. ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,448082431
