Snap2stamps error

ABraun · February 15, 2021, 8:39am

then the changes were not applied or in the wrong file.
Are you using the latest version of SNAP?

suribabu · February 15, 2021, 8:43am

I’m using latest version SNAP8.0.3

Please check it once.

ABraun · February 15, 2021, 8:45am

and the snap2stamps scripts make use of the xmls in this folder or is there another instance of the folder elsewhere?

suribabu · February 15, 2021, 9:02am

While running this Snap2stamps python script in Ubuntu, I just copied graphs and bin folder to my working directory. Then i processed

python2 slaves_prep.py project.conf
python2 splitting_slaves.py project.conf
the above two ran successfully,
but while running the below step is is creating error,
3.python coreg_ifg_topsar.py project.conf

snap2stamps21920×1080 511 KB

Is there any path I have to set or no need?

suribabu · February 15, 2021, 9:05am

Sorry i forwarded wrong image, below one is the correct one.

suribabu · February 15, 2021, 9:08am

This is my project.conf file in bin folder

ABraun · February 15, 2021, 9:34am

please also modify this line in the coreg_ifg_computation_subset.xml file

suribabu · February 15, 2021, 9:55am

Thank you so much ABraun, You are excellent in problem solving.
I think it was running fine.

Please give me solution for the above error?

s.savastano · March 3, 2021, 10:49am

Hi @suribabu,
as you can read on the forum and post by @ABraun, since Monday there is a problem with “apply Orbit File” and we are all waiting for
an update from the developers.

Regards,
S Savastano

suribabu · March 3, 2021, 10:50am

Thank you so much.

From last one hour onward it is showing like this. with coreg_ifg_computation_subset.xml also same issue. Please check it once

suribabu · March 5, 2021, 11:08am

I have around 29 SAR images, From last one hour onward above posted command is running but still there is no output is created for single image ( coregister folder and interferogram folder) .

ABraun · March 5, 2021, 12:16pm

maybe related to the DEM used in the BackGeocoding? A process related to digital elevation models is taking forever to finish

suribabu · March 6, 2021, 6:29am

Thank you so much ABraun it’s working now.

suribabu · March 8, 2021, 4:37am

Dear ABraun
S1-TOPS split is not running. please check it once. I installed all the updates now it is SNAP8.0.3.

ABraun · March 8, 2021, 5:37am

I can’t see an error.
Maybe your disk is full? Restatting SNAP could also help.

suribabu · March 8, 2021, 7:36am

No still 2TB free space is present, it took around 10 minutes to complete this step.
