Workflow between SNAP and StaMPS

Exelente, Katherine, por primera vez estarè trabajando unos interferogramas, ya elabore unos modelos pero me arroja cierta coherencia en el agua, situacion que no se si sea normal, como le hicistes para reducir o establecer que no surgiera efecto en el agua. Saludos. Oliver

Hi Oliverius,
thanks for participating in the forum. But please stay in the English language. Then everybody can understand it.

Quick automatic translation:
Excellent, Katherine, for the first time I will be working on some interferograms, I already made some models but it gives me a certain coherence in the water, a situation that I don’t know if it’s normal, as you did to reduce or establish that there was no effect in the water. Greetings. Oliver

Of course, thank you very much, I understand that when using the c band that has a wavelength
of 3-6 centimeters, which in theory would be more applicable for areas without vegetation cover so that it has direct contact with the surface, as has been your experience regarding the application of differential Interferometry in areas with vegetation cover and slow waters. Thanks Oliver

Someone in the forum who has a summary of the processing of interferograms with snap / Stamps and their add-ons for windows, I am thinking of working with Sentinel 1, specifically for a hydropower reservoir. Oliver

It’s already existed under this thread or other similar one, please find it.

Please have a look here:

thank you, these are great news. I would be very interested in this preliminary version, too!
see: ,

To be extra clear:

i have not yet found any succes of using StaMPS on Windows by compiling it, i would highly recommend to skip the painful trial and error and move to linux. can ofcourse be dual boot as well.

Yes, it seems windows has not only problem in this terms, however, python and related issues, Linux is the solution.

Dear all.
According to many guidelines, i have to choose optimal master image near time center and average baseline from collected data. So how about my choice showing on this figure?

for single-master approaches, one which lies in the temporal and perpendicular center is mostly selected. I would probably have taken the same.

Anyone faced into this?

Probably you are working with a single burst, right? If so, delete the ESD operator from the xml

I believe your error will disappear

Great!!!. Thank you
It works, after edited 2 xml file like this.

But is there any difference side of processing result quality?

No difference.
If you work only with 1 burst, ESD must not to be applied.

hallo I follow your workflow to prepare sentinel images for stamps processing.
Everythings seems ok but no insar_master_date folder was created!
The mt_prep_snap doesn’t find the slc.par files.
do you know wherw I was wrong?
I’m sorry, maybe is a simple thing but I’m new in this field! :slightly_smiling_face:
thank you so much

just to go sure: did you run as the last script?
also to go sure: the folder name will not contain “master_date” but the date of your master in this order: yyyymmdd. For example, the folder will be INSAR_20190721 for a master image selected on 21.07.2019.

If you work only with 1 burst, ESD must not to be applied.

I followed those steps.
And final export result was like this

I have used:

  • 53 images.
  • Stamps v4.1b, Snap 7, ubuntu server 16.04, gcc 4.8, matlab 2016b, python 2.7
  • IW2, single burst
  • All previous steps didn’t get any errors
  • Here is my config file.
  • mt_prep_snap script doesn’t work. My results empty in my patch_1 folder
    image image

can you please also share the mt_prep_snap command you used?

Regardless of the error, I recommend creating a separate folder for the StaMPS processes. Simply create a new directory (at any location) and execute mt_prep_snap here. This helps you to keep the structure clean and doesn’t mix up the original files exported from SNAP with the ones created by Matlab.
