This is tangentially related to the to_geotiff() discussion.

We're using intake-xarray to read a year's worth of Sentinel-2 Scene Classification Layers into a DataArray, doing some processing, and then writing the output to a single band GeoTIFF. When writing the output, we'd like to preserve the colormap of the original underlying data. xarray-intake uses xarray to read the dataset, so thought it might be useful to add support in open_rasterio() to read and load src.colormap(1) and src.colorinterp into the attributes of the DataArray. My thinking is that if in the future the community ends up wanting to add a to_geotiff() method, reading the src colormap and colorinterp might be useful.

Before adding tests, I thought I'd submit the PR to see what others thought about adding this functionality. If there's support for this, I'm happy to add any needed tests or documentation.

  • [ ] Tests added
  • [ ] Fully documented, including whats-new.rst for all changes and api.rst for new API
