Error using sen2cor v 2.3.0 with DEM

Optical Toolbox sen2cor
#1

I have tested the new release of sen2cor (v 2.3.0) on Unix.

The problem reported in this post Using DEM for L2A_Process - Error seems to be fixed by using subprocess.Popen.wait().

I still have problems using DEM, the reported error is:

RuntimeError: No such file or directory

The problem occurs using both one or multiple cores.
If the DEM option is set to “NONE” the process is going through without errors (using both one or multiple cores).

Any solutions?

Sen2Cor over special region by accurate DEM not SRTM DEM
#2

I had the same problem with sen2cor v2.4.0.

The solution I found was to set the ‘DEM_folder’ in the sen2cor ‘L2A_GIP’ configuration file to the ‘/home’ folder. Maybe some Linux OS privileges may limit the use of other folders while importing the DEM files.

Update for users who have this problem on sen2cor version 2.5.5.

The configuration file ‘L2A_GIPP.xml’ now specify that the ‘DEM_Directory’ should be located in the sen2cor home folder:

 <DEM_Directory>/home/username/sen2cor/2.5/dem</DEM_Directory>
<!-- should be either a directory in the sen2cor home folder or 'NONE'. If NONE, no DEM will be used -->

Location of the sen2cor home folder is set in file ‘L2A_Bashrc’ with variable ‘SEN2COR_HOME’.
In example:
SEN2COR_HOME=/home/username/sen2cor/2.5
