Thanks for the following tutorial, it helps to download additionnal bands. As we can see in this tutorial, there is a perfect match between train image and image downloaded through STAC API for chip_id=mtmo
However we can notice that datetime differs:
Train: 2020-04-30 08:43:07+00:00
STAC API (closest one): 2020-04-30 08:15:59.024000+00:00
How is it possible to have the same image (cloud locations) with around 30 minutes time shift? Clouds should have moved.
In the following thread we can read that:
datetimecomes from Sentinel-2 meta data. It’s possible it won’t match exactly to the chip in the planetary computer.
So, can we rely on date time provided? Are they really comparable? A time range = 2x30min provided on search items is calibrated to make sure we can find an accurate match?
Update: 2x30min captures 93% of existing chips.
