Snap2stamps package: a free tool to automate the SNAP-StaMPS Workflow

mdelgado · April 28, 2020, 10:49am

had you checked the log while doing the splitting?
the message says that expects split products… so probably there was something wrong…
no issues with S1A-S1B

gokulanand · April 28, 2020, 11:00am

Split_proc_stdout.log says split slave successfully completed in each folder whereas in coreg_if_proc_stdout.log ‘error in computing coregistration and interferogram generation of splitted slave’

mdelgado · April 28, 2020, 12:26pm

Well… again. The error says Split product expected. So please check what you did or its results.
Can you open some in SNAP and see it?

gokulanand · April 28, 2020, 12:42pm

mdelgado · April 28, 2020, 12:55pm

is this the original footprint?
Or the splitted one?

Please put one original footprint next so we can see…
I agree than one image counts 1000 words, but please do not save letters to explain what you got, or it would be more difficult to help

yzxtll · April 28, 2020, 1:11pm

Hi,ifg and coreg directory is empty，attacted project.conf and split_proc_stdout.log and coreg_ifg_proc_stdout.log,please help me,thank you .

The splitting looks fine to me.
Can you check the master?

yzxtll · April 28, 2020, 1:21pm

the master and splited slaves all looks fine. I wonder maybe the reason is the name of master which is MASTER=/mnt/hgfs/PSI_proc/master/20191121_Spl_Orb.dim?

Sorry for inconvenience caused due to lack of information.

I also noticed this. Maybe it is required to stick to the actual name of the master proposed by SNAP, as suggested by @mdelgado in this post:

yzxtll · April 28, 2020, 1:35pm

thank you @ABraun ,I’ll follow your instruction and have a try ,feedback will be very soon

mdelgado · April 28, 2020, 2:13pm

Not sure but the splitted ones, do not look like to contain full subswath. How had you splitted them?
Can you show the split2run.xml

yzxtll · April 28, 2020, 2:40pm

maybe @gokulanand makes the same fault which result in the same error ,it is about the master file as a zip format not a dim one .

mdelgado · April 28, 2020, 2:46pm

@yzxtll is right. Thanks for pointing it out

gokulanand · April 28, 2020, 4:41pm

I saved master as dim product and changed the file type to .dim. Still I get the same error. I have this doubt,

SNAP GPT

GPTBIN_PATH=/application/pi/snap/bin/gpt

the gpt is not a folder in my system it is a file

. Should I change the path by removing ‘/gpt’ ?

ABraun · April 28, 2020, 4:57pm

If the scripts were already called correctly (as you have shown us above), the gpt is not the problem.

You have to pre-process the master:

Apply TOPS Split
Apply Orbit File

stick to the name that SNAP suggests and enter the full path to the master in the config file.

MASTER=Data/Ascending/project/master/S1A_IW_SLC__1SDV_20200129T100634_20200129T100701_031014_038FF7_6B11_Split_Orb.dim

Thank you for the correction. I have new problems coming up in ESD. After a quick overlook throughout the trail I come to know that it is because of SNAP 7 and snap2stamps is mainly made for SNAP 6. I will try to update the scripts by the instruction given by @mdelgado. If not successful I will wait for the latest snap2stamps update. Thanks again for the support.

hello,
did it work out?
i tried to take the full sub-swath so the processing took much time and at each ifg it gave me an error: japa heap space!

yzxtll · May 10, 2020, 3:33pm

I’ve run a snap2stamps stack of 26 images ,When I download a new S1SLC image ,Could I createa new a directory named image date(eg:20200507) into slaves folder and copy the ZIP image(eg:S1A_IW_SLC__1SDV_20200507T103622_20200507T103649_032458_03C23E_7AC5.zip) into the directory manully, then run step 2 “python splitting_slaves.py project.conf” skipping “python slaves_prep.py project.conf”?

ABraun · May 10, 2020, 4:09pm

yes, if you stick to the folder structure, you can skip the slaves_prep command. However, the current configuration runs later commands (splitting_slaves) for all data in the split folder, regardless if the outputs already exist or not.

This is the work-around:
