I'd like to add to this discussion the issue I brought up here #2288. It is something that could/should probably result in a new xarray add-on package for doing these type of operations. For example, I work on the pyresample and satpy projects. Pyresample uses its own "AreaDefinition" objects to define the geolocation/projection information. SatPy uses these AreaDefinitions by setting DataArray.attrs['area'] and using then when necessary. This includes the ability to write geotiffs using rasterio and a custom array-like class for writing dask chunks to the geotiff between separate threads (does not work multiprocess, yet).

I would love to see these additions (or some recipies on how to do it as xarray stands). As a note, I figured out a rather simple way using with rasterio.open(...,'w',**profile) to effect the write. That might help in the short to medium term.

I am also interested in looking at your Pyresample and well as something similar to the morphological operators (in this context specifically measure).

Best of success!
