BUG: Create fallbacks for broken Sentinel-2 products #34

Closed remi-braun closed 2 years ago

remi-braun commented 2 years ago

Manage partially broken Sentinel-2, downloaded from AWS:

it happens that MTD_MSIL2A.xml exists but is empty (see S2A_MSIL2A_20170331T103021_N0001_R108_T32UMV_20190508T053047.SAFE\MTD_MSIL2A.xml)
it also happens that the detector footprints have empty geometries (see S2A_MSIL2A_20170331T103021_N0001_R108_T32ULU_20190508T053054.SAFE\GRANULE\L2A_T32ULU_A009257_20170331T103340\QI_DATA\MSK_DETFOO_B04.gml)

Create fallbacks for nodata and existing but empty datatake mtd.

Seems that if the DETFOO is empty, some bands are also corrupted. But in the doubt, products with empty DETFOO are now handled.

Sentinel-2 product without metadata are also now supported, with the condition of a well formatted filename.
