Sen2cor 2.11 - AttributeError: ‘bool’ object has no attribute ‘SPACECRAFT_NAME’

iliasmachairas · August 2, 2024, 11:25am

I use sen2cor 2.11.00 to correct some Sentinel-2 images atmospherically via Python on windows. The problem is that for some recent images (in July/2024) I got the following error. For other images (taken one year before), it worked fine.

I have checked other relevant posts such as https://forum.step.esa.int/t/sen2cor-2-8-fails-on-product-from-early-2016-bool-object-has-no-attribute-spacecraft-name/16046, https://gis.stackexchange.com/questions/335665/sen2cor-l2a-process-not-working-returns-strange-error without success. They solutions are related to older versions of Sen2cor. Any idea?

Dear, all,
I am running Sen2Cor v2.12.03 on a Docker container based on the image condaforge/mambaforge:24.9.0-0 (Ubuntu). If I try to use the new Sentinel-2 images, I receive the same error:

Could you help me?

Thank you for your help.

Dear @aurgs,

Welcome to this forum,

Could you please open a new ticket and attach the full log of your Sen2Cor processing (including the execution command with S2 L1C Product name) and check if you are using the correct updated L2A_GIPP ? You can attach your L2A_GIPP used to the ticket.

Cheers,
@Sen2cor_dev_team

Was there ever any resolution to this issue? I haven’t used SNAP and Sen2Core for a while and am getting this same error while trying to process S2 L1C images.
(using SNAP 9.0.0 and Sen2Cor 2.11.0)

Hello,

I am getting the same Sen2Cor error on a Sentinel-2C Level-1C product, yet with a newser Sen2Cor Version.

Environment

Sen2Cor version: 2.12.04
OS: Linux
Input product: S2C_MSIL1C_20260220T095031_N0512_R079_T33UXQ_20260220T114831.SAFE

Error Message

Traceback (most recent call last):

AttributeError: 'bool' object has no attribute 'SPACECRAFT_NAME'

Checks already done

The datastrip XML exists:

…/S2C_MSIL1C_20260220T095031_N0512_R079_T33UXQ_20260220T114831.SAFE/DATASTRIP/DS_2CPS_20260220T114831_S20260220T095033/MTD_DS.xml

XML is well-formed:

xmllint --noout "$SAFE"/DATASTRIP/*/MTD_DS*.xml

This returns no error.

The datastrip metadata contains SPACECRAFT_NAME:

<n1:General_Info>
<Datatake_Info datatakeIdentifier=“GS2C_20260220T095031_007628_N05.12” metadataLevel=“Brief”>

</Processing_Info>
</n1:General_Info>

The product structure looks normal; find "$SAFE/DATASTRIP" -type f shows:

…/DATASTRIP/DS_2CPS_20260220T114831_S20260220T095033/MTD_DS.xml

…/DATASTRIP/DS_2CPS_20260220T114831_S20260220T095033/QI_DATA/SENSOR_QUALITY.xml

This makes me think the issue is not a missing SPACECRAFT_NAME tag, but that Sen2Cor’s internal datastrip parser returns False before reaching that field.

Has anyone seen this with Sentinel-2C products at PB 05.12 in Sen2Cor 2.12.04, we also experienced the same error for Sen2Cor 2.12.03?

Is this a known bug, and is there a workaround or patch available?

Thank you.

We suspect that the reason of your error is that in your Sen2or processing, a former version of L2A_GIPP.xml, incompatible with last Sentinel-2 Level-1C product based on PSD 15.1 was used. See point#1 of Frequently Asked Questions:

1) L2A_GIPP important information

Please be aware that a new installation of Sen2Cor 2.x does not replace the L2A_GIPP.xml that is located in the existing destination folder (e.g. C:\Users\username\Documents\sen2cor\2.x).
Please be sure that the L2A_GIPP.xml is up-to-date with the Sen2Cor Version you are using.
Please use the command line --GIP_L2A path_to_the_L2A_GIPP.xml to force the use of the chosen L2A_GIPP.xml

Default L2A_GIPP.xml is shipped in:
Linux in: ../Sen2Cor-02.12.04-Linux64/lib/python2.7/site-packages/sen2cor/cfg/L2A_GIPP.xml
Windows in: C:\Sen2Cor\Sen2Cor-02.12.04-win64\Lib\site-packages\sen2cor\cfg\L2A_GIPP.xml

What is missing in former L2A_GIPP.xml is the part pointing to the new PSD 15.1 of Level-1C PB05.12:

<PSD_Scheme PSD_Version="15.1" PSD_Reference="S2-PDGS-CS-DI-PSD-V15.1_Schema">
        <UP_Scheme_1C>S2_User_Product_Level-1C_Metadata</UP_Scheme_1C>
        <UP_Scheme_2A>S2_User_Product_Level-2A_Metadata</UP_Scheme_2A>
        <Tile_Scheme_1C>S2_PDI_Level-1C_Tile_Metadata</Tile_Scheme_1C>
        <Tile_Scheme_2A>S2_PDI_Level-2A_Tile_Metadata</Tile_Scheme_2A>
        <DS_Scheme_1C>S2_PDI_Level-1C_Datastrip_Metadata</DS_Scheme_1C>
        <DS_Scheme_2A>S2_PDI_Level-2A_Datastrip_Metadata</DS_Scheme_2A>
    </PSD_Scheme>

Please let us know it is solved your issue.

Cheers,
