Sen2Cor standalone command line

[PamelaP]

Hi! I am new to phyton and sen2cor. I have been trying -so far, unsuccessfully- to install the plugin and run it. I am using windows 10. First i tried Sen2Cor 2.4. standalone with snap, but it didn’t work. At the begging there were some errors with the Home and the Bin, which i tried to solve following these treads:

Sen2cor install (win64): issues with path environments _HOME, _BIN

Hi kyril23, Thanks for posting. Unfortunately it didn’t work. Sen2cor in SNAP shows the same message: > Before executing the tool, please correct the errors below: > Variable SEN2COR_HOME is not set > Variable SEN2COR_BIN is not set After which this window appears: [image] Any clue about how to configure the system variables value from here? Many thanks, Francesc

KeyError SEN2COR_HOME

Continuing the discussion from Workaround for sen2cor bug at resolution 10 m, with a nod to this “unrecognized variable” topic: If you get a KeyERROR 'SEN2COR_HOME' you might want to make sure that you installed Sen2Cor according to the SETUP.pdf, and that you have an environment variable called SEN2COR_HOME. To check for that environment variable on a Windows system, you can either a) follow the instructions on How To Manage Environment Variables in Windows (XP) and Right-click My Compute…

I have tried uninstalling and re installing several times. According to most posts, it will only work on command line. So far i’ve managed to install it, but i am not sure how to execute the atmospheric correction. Can anyone tell me how to do it?

you are already close to it.

Last thing you need to do is to tell sen2cor where your data is located.
Simply open the command line in a folder where your S2 data (the folder ending with .SAFE) is located.
There you type:
L2A_process --resolution 10 NameOfTheFolder.SAFE
Replace _NameOfTheFolder.SAF_E with the actual folder name. Instead of typing it down, you can enter the first letters and then hit the tab key to complete the full path name.

Hello!
In promtp window , i write L2A_Process and at the end there is an error too few arguments.
What can i do?
Thanks in advance
R.

[ABraun]

please just read my post above yours.

[rinokeros]

i read the post. The environment variables are ok, i cannot find out the problem. Anyway, I tried to install the sen2cor from anaconda.
After the L2A Process --help, there is an import error : No module named gdal, do you know what can i do for this?

thanks in advance

I have downloaded the stand alone version of sen2cor, put it in C:\Users\myname\AppData\Local\Sen2Cor-2.4.0-win64 and added this to system path. When I type L2A_Process.bat at the cmd I get a list of options, so it seems to work.

When I try:
L2A_Process.bat --resolution 10 G:\S2A_OPER_PRD_MSIL1C_PDMC_20160921T193747_R051_V20160908T105022_20160908T105416.SAFE

The result is:

What can I do?

did you forget the : in your path G:\ ?

[ABraun]

@rinokeros

i read the post. The environment variables are ok, i cannot find out the problem.

“too few arguments” means that sen2cor was installed correctly but doesn’t know what to do.

The gdal error however is more severe: try to enter conda install gdal and run again.

[annettew]

“did you forget the : in your path G:\ ?”

No, that was a typo in the post, not in the process. If I forget : then the file is not found.

[PamelaP]

Thank you! I tried but it didn’t work. It shows this error:

C:\Tabaconas\Sentinel>L2A_process --resolution 10 S2A_MSIL1C_20170606T153621_N0205_R068_T17MPQ_20170606T154217.SAFE
“L2A_process” no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

Which translates into: “L2A_process” is not recognized as an internal or external command,
program or batch file executable.

Thank you again!

[ABraun]

in this case you need to add the path of the folder where sen2cor is installed to your system’s PATH variable:

It took me around 45 hours to proccess sen2cor by command line. For 18 hours it was working slowly but normally and then when it reached 98% it would come back to 97,6%. After next 27 hours it kept on going to 98% and then going back to 97,6%. After that I had this error. There no images in new folder, so it was working for 45 hours for nth. To be honest I am very disappointed that sen2cor is not working just like the last version…

I am able to process the 2017 files but unable to process any files that date from before the name change to shorter names. The error is :
File “src/lxml/parser.pxi”, line 613, in lxml.etree._raiseParseError (src\lxml\lxml.etree.c:103967)lxml.etree.XMLSyntaxError: Document is empty, line 1, column 1.
Could something be wrong with the xml? What can I do to resolve this? If I search for the error on the forum I get 1 result and that is my unanswered question. I have tried to install older versions of SNAP and sen2cor but have not been able to process any older images yet.
