Erreur with sen2cor at resolution of 10 m

Optical Toolbox sen2cor

Hello @ABraun ,

I installed the last version of sen2cor (2.3.0), when I do the processing of a sentinel-2 image with 10 m resolution I receive the following error

Process L2A_ProcessTile-1:

Can you help me please :slight_smile:

this indicates that you probably don’t have enough RAM installed.
You could try to run sen2cor on 60m and check “scene only” (this should require less RAM) to see if it technically works.

Besides that, there is a sen2cor update to version 2.3.1 which you could try first:

Thanks a lot for your help @ABraun , I think it’s a problem with RAM, I have 4Gb installed and I think it’s not enough

Dear ELHACHIMI

I think I meet a same problems with sen2cor at 10m. How do you solve your problem?

Thank you a lot

Hi @derTraum ,
try to use Sen2Cor via command line. Sometimes in SNAP it doesn’t work

Best regards.
