@benbovy I also agree that a data structure that encapsulates a scale into a nice API, where you set the scale currently desired, and the same Xarray Dataset/DataArray API is available, and that scale can optionally be lazily be loaded. Maybe an Index as proposed could be a good API, but I do not have a good enough understanding of how the interface is used in general. What would be other examples like ImagePyramidIndex, outside of the multi-scale context? Should something like Scale be used instead?

Regarding dynamic multi-scale, etc., one use case of interest is where you are interactively processing a larger-then memory dataset, and want to visualize the result over a limited domain on an intermediate scale.
