Hi all,

most bands of Sentinel-2 are provided in multiple spatial resolutions (10m, 20m, 60m). The current implementation does not handle this - only the latest asset in the list of image files is listed in the STAC document (the previous ones are overwritten because of the same asset key). I guess this is not intended.

The variable band_id returned should be unique - at least when describing the original Sentinel-2 dataset, e.g. B02-10m (similar to the auxiliary images, such as visual-10m, visual-20m, visual-60m). This would reference all image files available. Otherwise only the image file with the highest spatial resolution (not the latest in list) could be referenced as an asset.
