sen2cor on Mac OSx

Optical Toolbox sen2cor
#1

Hi all,

I’m trying to use sen2cor. I’ve installed SNAP today, and then tried to install sen2cor according to the setup.pdf, including installing anaconda. I’ve then installed through tools>plugins in SNAP, however when I try and run it on an image, I get an error that SEN2COR_HOME and SEN2COR_BIN are not set?

Any suggestions to solve this?

Thanks!

Cannot set sen2cor environment variables on OS X (SEN2COR_HOME etc)

Hi,

SEN2COR_HOME and SEN2COR_BIN are defined in the System Variables section of the adapter editor. The adapter editor should open right after you have the message saying SEN2COR_HOME and SEN2COR_BIN are not set.

The values you have to set for SEN2COR_HOME and SEN2COR_BIN variables are explained in the setup.pdf you can find here: http://s2tbx.telespazio-vega.de/sen2cor/SETUP.pdf

There are a few graphical problems with the “adapter editor” on Mac OSx with the Beta8 but you should be able to edit these variables anyway.

Hi Nicolas,

working with the beta8 version I was facing the same problem as hek17.
Unfortunately, I am unable to edit the SEN2COR_BIN value in the “adapter editor” (it always returns to an empty cell after editing).
I also found that the GDAL_DATA location indicated in the SETUP.pdf (by telespazio) does not correspond with L2A_Bashrc setting.

SETUP.pdf
GDAL_DATA: this is a pointer to the directory
where the GDAL coordinate system info is stored. This is located
in the “site-packages/osgeo/data/gdal” folder of Anaconda. Do not
change this.
L2A_Bashrc
export GDAL_DATA=/Users/wulf/anaconda/share/gdal

Do you have any clues?

best,
Hendrik

Hi Henrik,

Your problem with SEN2COR_BIN is a known issue (see https://senbox.atlassian.net/browse/SNAP-292). It will be fixed in the next version, for the moment you will have to edit the .snap/etc/snap.properties file in your home directory.
I don’t know about the GDAL_DATA location but you shouldn’t need to change this. May be @umwilm has an idea.

dear User,
the entry given in the L2A_Bashrc for GDAL_DATA is the correct one. The sentence in the setup.pdf is wrong. I will update the setup.pdf with the correct information. Thank you for pointing to that issue.
