To make building the documentation a bit faster (by 5-10 minutes for me), this adds a xr.tutorial.open_rasterio function with a signature and behavior that is almost identical to tutorial.open_dataset (when we replace the open_* functions with open_dataset(..., format="...") we should do that for the tutorial functions, too).

It uses requests.get instead of urllib.request.urlretrieve so that would be a new dependency. I'm not sure if that's an issue since it's installed in the bare-minimum CI's environment.

The tutorial.open_dataset code could be rewritten to use the same structure but I wanted to get feedback on open_rasterio first.

Edit: I also changed the default cache directory to ~/.cache/xarray_tutorial_data with a fallback to the old default if ~/.cache does not exist

  • [x] Closes #3986
  • [x] Tests added (but that's just a comparison between cached and uncached)
  • [x] Passes isort -rc . && black . && mypy . && flake8
  • [ ] Fully documented, including whats-new.rst for all changes and api.rst for new API
