[x] this function returns only unique L1C products, as not all Sentinel-2 images are processed to L2A level within CDSE
[x] for some reason, the existing scihub orientated function, queries_and_downloads.filter_unique_l1c_and_l2a_data() does not filter dataspace derived L1Cs, returning uncapped L1Cs and L2As. In the interest of time, the alternative unique filtering function was created.
Changes:
queries_and_downloads.filter_unique_dataspace_products()
queries_and_downloads.filter_unique_l1c_and_l2a_data()
does not filter dataspace derived L1Cs, returning uncapped L1Cs and L2As. In the interest of time, the alternative unique filtering function was created.
