Unable to open a UTM zone of 9 L1C tiles

Optical Toolbox
#1

Hi
I’ve just tried to open SciHub product from yesterday (S2A_OPER_PRD_MSIL1C_PDMC_20160909T074155_R046_V20160908T024322_20160908T024321.SAFE) by opening the XML in the usual manner. The product contains two UTM zones: UTM 50 (9 Tiles) and UTM51 (1 Tile). I can open the UTM51, but not the UTM50. My messages.log (attached) provides the following message (which is incomprehensible to me :slight_smile: )

messages.log (44.2 KB)

Any clues?

Hi Jan,

thank you for the report. I have just reproduced the error and discovered a bug in the mosaicking of the angles that affects to some products. We are working on it, the fix will be part of the next module update.

Hi again Jan,

Analysing the product in detail, i have seen that the granule S2A_OPER_MSI_L1C_TL_SGS__20160908T082050_A006335_T50PRA_N02.04 has an incomplete metadata. If you open the file
"[]\S2A_OPER_PRD_MSIL1C_PDMC_20160909T074155_R046_V20160908T024322_20160908T024321.SAFE\GRANULE\S2A_OPER_MSI_L1C_TL_SGS__20160908T082050_A006335_T50PRA_N02.04\S2A_OPER_MTD_L1C_TL_SGS__20160908T082050_A006335_T50PRA.xml " with a text editor, you can see that there are only angle data for the bands 10, 1, 2 and 7 (and only one detector per band).
We are going to fix the code to notify this correctly to the user and avoid the exception, but i think in this case there is also a problem with the product.

Cheers

Omar.
