Order of bands in the dataset

#18
by Scheur-endergelijke - opened

Hi,

I’ve been working with the Sentinel-2 dataset and want to be 100% sure how the spectral bands are ordered under each of the provided keys before I stack them into a single tensor. My current understanding is:

* 10m (1 bands): NIR → shape (1, 384, 384)

* 20m (6 bands): six 20 m bands → shape (6, 192, 192)

* 60m (2 bands): two 60 m bands → shape (2, 96, 96)

* rgb (3 bands): Red, Green, Blue → shape (3, 384, 384)

* scl (1 band): scene classification → shape (1, 192, 192)

…but I’d like to confirm:

Under the rgb key, is the order always strictly (R, G, B)?

Under the 10m key, what band is represented here?

Under the 20m and 60m keys, is there a documented order (e.g. sorted by wavelength: B05→B07→B8A→B11→B12 for 20 m; B01→B10 for 60 m)?

For reference on the band wavelengths and typical stacking conventions, see

Any clarification or pointer to how the order has been decided when creating the dataset would be greatly appreciated.
