load_stac : apply rescale and offset or not?

[clausmichele]

@ValentinaHutter @GeraldIr @SerRichard
The stackstac library allows to automatically rescale the data if the raster extension is provided and if the scale and offset values are set:
https://github.com/gjoseph92/stackstac/blob/694c68646a685abc8f3455d6b28fe121e18ae775/CHANGELOG.md?plain=1#L4

like here: https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a/items/S2A_32TPS_20230602_0_L2A

After the latest update, rescale is True by default and therefore it changed the values I was expecting to get.

Would we have better to set rescale=False by default?

@jdries do you apply scale and offset in load_stac at VITO?

The decision is not to apply scale and offset automatically. See discussions here Open-EO/openeo-processes#503 and related PR fixing the process definition here: Open-EO/openeo-processes#512
