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


#163

Hallo @mdelgado thank for snap2stamps.
I already run splitting_slaves.py and slaves_prep.py it’s going well no have problem. But when I try coreg_ifg_topsar.py I found some problem:
Error: [NodeId: Subset(2)] Operator ‘SubsetOp’: Could not parse geometry.

can you tell me what’s wrong with my step?
I already try various name format for master.

error:

master name format:
image

Thank for everything…


#164

It could be related to the coordinates defined in the config file. Can you please share it here as well?


#165

Thanks @ABraun. In fact I suspect that the error should come from there.
Let us know


#166

Thank you @ABraun and @mdelgado for your reply.
I just fix my config file, but found another error I think it come from my memory not enough.

image


#167

The Master image should not contain IW3…
I think this is creating the issue.
I hope this helps
Best regards


#168

Hi,

Do you have the Docker image available somewhere on Docker Hub? @andretheronsa I am trying to achieve exactly the same.

First of all, thanks for your work on snap2stamps @mdelgado ! When I try to run the scripts with 2 sample S-1 images, the scripts run without error, but they do not produce any output. When trying coreg_if_topsar.py script, I get the following error:

 Error: [NodeId: Subset(2)] Operator 'SubsetOp': Could not parse geometry.

Here is my config file:

Could the problem originate in not specifying a BBOX? Or is it not necessary?

Thanks


#169

Exactly. You should either defined the BBOX in the project.conf or change the graphxml template from the coreg_ifg_computation.py to use the xml without subset in the name.

Let me know


#170

Works great! Thank you. I also used the scripts in Python 3, after some simple adjustments, which works fine.


#171

Do you feel like contributing on the next package version for supporting also python 3?
Feel free to share with us your code. Now I am just developing new improvements but always only for the version 2.7.

Thanks


#172

@mdelgado Yes I would love to! I will send you the python 3 code for the current version and would not mind contributing for the next package version. Just tell me how to get in touch.

Thanks


#173

hello~~Thank for snap2StaMPS again.
I wanna ask a question about “SNAP2StaMPS_CONFIG.bash”
Should I add it to ~/.bashrc before the python process?


#174

Is it not strictly necessary to use the SNAP2StaMPS_CONFIG.bash, you could directly add to the PATH variable the bin folder containing the python scripts of the package.

But once modified the SNAP2StaMPS_CONFIG.bash file (if you want to use it), yes, you can add it into the .bashrc for avoiding to load it every time.

I hope I have answered your question


#175

Thank a lot !!!
I just occur some error

I run 14 images for the process of splitting_slaves.
However, some images are fine, but some images are happening ERROR: invalid LOC header (bad signature).
I don’t know how to solve the error.
All the images are splitting well when running TOPS-split method in SNAP.


#176

could it be that image #3 from 21.07.2017 wasn’t correctly downloaded?
Check and compare the fize sizes and try to open this one in SNAP.


#177

In fact, that could be the reason.
The error log comes from SNAP and not from the scripts.

Let us know


#178

Hello @ABraun @mdelgado Thanks~~You are right!!
The problem come from image format that SNAP cannot read either.
The images of 2017 were all unzip, so I zipped the file for slaves.


renaming: S1A_IW_SLC__1SDV_20170421T100023_20170421T100053_016241_01ADB3_11F3.zip
But it failed, SNAP cannot read this kind of zip.
And I try to put all the upzip data in each slave folder also failed.

So I run the process of split and orbit in SNAP for each image and save the right format(include name) into ‘split’ folder.
It seem workable for next step(core_ifg_topsar.py)!!

THANK AGAIN!! I am going to try next step!


#179

very good!


#181

Dear all,
hope you can give me an advice what can be the problem. The first script (slaves_prep.py) was running fine, but when I try to start the second script I got the following error message (subprocess.py). Attached are the *.conf file and the error message. Thanks for your help!
OS: Windows 10


project_test.conf (598 Bytes)


#182

You should define in the project_test.conf the full path to the GPT executable (should be something like C:/Program FIles/snap/bin/gpt.exe )

I hope this helps
Please check and let me know.
Cheers


#183

Thanks a lot ! Your hint solved the problem.
