I have successfully processed an L1C dataset using the sen2cor cmd line. The L2A_Process was run with the --sc_only parameter since I am mostly interested in scene classification. I opened the resulting dataset in SNAP and was wondering how to visualize the scene classification? i.e. how do you arrive at the visualization shown in the attached?
Is this a mistake in the SEN2COR script or is there again some scaling problem in the data?
EDIT1:
Here a comparison of the spectral profiles of the bands 2, 3 and 4 in 10m-resolution before the SEN2COR-Correction, and then in 10, 20 and 60m resolution AFTER the atmospheric correction. Shouldn’t the 10, 20 and 60m-images be similar? I picked a forest Pixel in a homogenous region. The 10m result seems to be really off!
EDIT2: Another Question: Is there a reason why for the corrected dataset, Band 08 is only available in 10 m, where all other 10m bands are also written in 20 and 60m?
Hi,
I am getting only the post template files in my working directory. I am still unable to get L2A data from sen2corr each time I run it I get this snap error message. Any idea please. Thanks
i am trying to run Sen2cor (2.0.5) in SNAP (2.0-beta-08) as an external Tool.
I installed sen2cor sucessfully and the L2A_Processor is working on command line level.
If you need, i can provide my command line output from L2A_Processor.
I am working on a Windows 7 64bit machine.
I followed the discussion in the forum, but i am still having problems to create a L2A through the integrated sen2cor Tool in SNAP. Heres what i have done so far:
I renamed the root folder to: S2A_OPER_PRD_MSI_L1C_ to get rid of path length issues
Local Input path of the XML: D:\beck_ct\data\s2a\L1C\S2A_OPER_PRD_MSI_L1C_
I keep getting following error:
Is it possible that those errors are produced through the renaming oft the root folder?
You get this message because you chose to see the processor output. There is a message saying Metadata file is invalid because of compliance to PSD (the product spec) but ‘Application terminated successfully’ so apparently everything went fine. What you see is a warning message that is not related to the folder.
For the moment, no. @umwilm will tell you more about it.
Please notice that a new release of sen2cor (2.0.6) is now available, with a few important fixes. Be sure to update !
Hope you noticed that now with the latest SNAP 2.0, the scene classification data is read automatically.
It appears in the “Index Bands” category, and tuning the color manipulation can quickly get you to the visualization you want.
Also, for each class, there is a dedicated Mask that can be used in SNAP, so you can visualize each class independently.
The validation warning (error) currently appears due to a “mixture” of V12 and V13 in the L1C input data. This will be cleaned up in the coming version, as we currently received a new V13 Metadata scheme which must be integrated.
it does not have impacts on the generated output product.
thanks for clarification @umwilm! @jmalik: I recognized the new version of sen2cor you provided. Thanks for the advice!
General procedure for updating to a new version? I propose run install.py?
