SNAP warning error

[guermazi]

Hello,

I have different warning error generated by SNAP model, please help me to solve it:

error (1) SNAP is unable to read xml data
error (2) I can’t display sentinel-2 data in SNAP interface
error (3) the sen2cor extension dosen’t work correctly

It is not easy to help with little information about your system, data, version…

1. Open S2 files via File > Import > Optical > Sentinel-2 > L1C and select the xml file in the folder above. It is named like S2A_OPER_MTD_SAFL1C_PDMC[…].xml_. Select a resolution then.
2. If step 1 is done you can open the data, make an image composite or work with individual bands.
3. Please open Tools > Manage external tools > Sen2Cor > Edit and post a screenshot of the tab System variables

When I execute Step 1 I have the warning error N°1
It can’t read xml file

• the system is windows 7, 64 bits
• is sentinel2 data level L1C

For the first warning, it seems you are trying to open an xml file (*.aux.xml) which is not the product metadata file. Usually such files are produced after processing with other tools. Try to use the xml metadata file from the original product.

I have the same question for the third warning. Then I post the screenshot as it’s shown above.

you can replace the value for PYTHON_BIN by the full path to your python installation:

Sen2cor2.2.1 install error

Please check the full paths to your Keys: Are there any special characters. A second thing you can try is to place the full path of your python installation into your PYTHON_BIN: F:\Anaconda2\python.exe This helped in another case:

Worked here, for example:

Sen2cor doesn't perform the atmospheric correction and the strange interface?

Thank you very much! I found the bug ))). I had to set the path “С:\Anaconda2\python.exe” for PYTHON_BIN. )))

[MickyHuu]

Fine… I checked the full path and placed the full path of my python installation into PYTHON_BIN like this:

Since I think these paths have no special characters, I ran it again. However, it still told me Warning, the execution output like this:

attributeError…?

Thanks again.

[ABraun]

hm, at least the processing starts now.
About the attribute error I’m not sure.

Maybe this helps:

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

I also had this error. It turns out that Sen2Cor’s approach to picking up the metadata XML file within the product .SAFE folder is not particularly clever, so if you have any other XML files in there besides the {product}.xml file then it might pick the wrong one up. Delete any additional XML files in the {product}.SAFE folder, such as those generated by QGIS if you have previously opened/exported the L1C data, then run the script again.
