Please test the SBAS_snap2stamps

CDE · January 7, 2021, 1:25pm

Hi @dongyusen
Thanks for sharing with us SBAS to StaMPS
I would like to test , so that I have this Error in the first step of splitting_master_free. Please have look to my print Screen to fix my problem.

.

Cheers.

See the SOURFOLDER, IT SHOULD BE YOUR DATA FOLDER

Dear Dongyusen,

Please provide a clear processing steps regarding your code on SBAS_SNAP2StaMPS.

Thank you so much.

Shouldn’t LATMIN be smaller than LATMAX?

CDE · January 8, 2021, 8:36pm

Do you want to say that my data folder include all slaves and the master image??

Linya-Peng · January 9, 2021, 1:53am

Sorry, but this is not my txt, mine is here

the master splitting script work fine,but I got an error when I run the slave_splitting_free.py

the error continued appearting and I had to close the powershell window to shutdown the program. Can you help me?
Thank you in advance

Hi @Linya-Peng ,

I want to test SBAS_snap2stamps , and I got the same error when splitting slaves,
I read your configuration file. Does your folder testdata include all images (slaves and master)??, and what about the folder testinsar ??

Cheers.

Linya-Peng · January 11, 2021, 1:35am

Hi @CDE!
Yes, my folder testdata includes all images, both slaves and master. The folder testinsar is the project folder in which log file and result will be. By the way, which OS and python version did you use? I’m a windows user, and I’m not sure whether the error is caused by OS or python version.

Linya-Peng · January 11, 2021, 1:55am

Hi @CDE! Me again, I run the script in Ubuntu, and It seemed work well. My python version is python3.8. So I think the wired error was caused by OS.
Hope that can help you~

CDE · January 11, 2021, 7:35am

Hi @Linya-Peng , I’m a windows user too. My python version is 2.7

I will try the script in Ubuntu with python3.8 . Thanks for information

CDE · January 13, 2021, 1:01pm

Hi @Linya-Peng @dongyusen ,

which version of snap I must use in Ubuntu ??

when executing : sbas_topsar_ifg.py
I get this error :
Traceback (most recent call last):
File “sbas_topsar_ifg.py”, line 16, in
import numpy as np
ModuleNotFoundError: No module named ‘numpy’

Have you got an idea ??.

Thanks

ABraun · January 13, 2021, 1:46pm

numpy is a python package which is required to execute the script. You can install it afterwards: https://numpy.org/install/

Linya-Peng · January 13, 2021, 2:11pm

Hi CDE, I’m now using snap8.0 in Ubuntu

CDE · January 14, 2021, 2:48pm

Hi @Linya-Peng, @dongyusen, @ABraun

when I execute the command : sbas_topsar_coreg.py

I get this error :

As I have not developed or tested this script, I cannot help much.

But there is a wiki article on this type of error: https://senbox.atlassian.net/wiki/spaces/SNAP/pages/321126402/Collection+of+FAQs#On-Linux-I-get-the-error-org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

Linya-Peng · January 15, 2021, 4:13am

I met the same error, and I tried to install libgfortran.so.5, but another error occured and I’m now still stuggling with it.

Linya-Peng · January 17, 2021, 7:55am

Hi @dongyusen
I loaded the ‘sbas_topsar_coreg.xml’ graph and found that there was no operator connected after ‘enhance spectral diversity’

Could you please explain why the graph is designed like that? (I’m a beginner in InSAR, maybe I asked a stupid question )
Thank you in advance

I have processed 56 Sentinel 1 data with sbas_snap2stamps and it worked fine, but there are some things to note:

This is different from snap2stamps which separate slave and master SLC data folders, sbas_snap2stamp combines master and slave file folders.
in the configure file, the AOI clip area must be filled in properly, the size must not be more than AOI BBOX DEFINITION.
The order of work:

splitting_master_free
splitting_slave_free
sbas_topsar_coreg
sbas_topsar_ifg
sbas_export

check the baseline with plotbaseline.py, if something is not connected, you can add it to the sbas_add file, then run sbas_topsar_ifg by taking longer temp_baseline on the configure file.

When setting mt_prep_snap rg_patch and az_ptch, for example:
mt_prep_snap 20150119 / min / g / process / stamps / bandung_basin / 149_615 / SBAS / INSAR_20150119 / SMALL_BASELINES / 20141108_20151103 / 0.6 5 5 50 200

this is because all data can be stored and processed.
This is most important, if the stamps are downloaded from https://github.com/dbekaert/StaMPS/ when the sb_parm_initial command is activated or small_baseline_flag: ‘y’ in stamps (1), stamps step 1 will occur an error.

download and replace the sb_load_initial_gamma.m file from https://github.com/limingjia92/StaMPS/blob/patch-2/matlab/sb_load_initial_gamma.m from the matlab folder.

configure file

sbas_bb_149_613
sbas result

.
.
.
and I already process with ps insar
ps_bb_149_613
ps result

dongyusen · January 18, 2021, 10:40am

I had update the sbas_topsar_coreg.xml file, please download the new file.
thx!
