Linux Installation using StaMPS and S-1 data


#63

Hello all. I’m having a hard time running Stamps here. Can anyone tell me what’s wrong? Thanks


#64

Finally solved it. my area of interest was too small. moreover, snap had added an extra layer to my stacks without any reason. So I removed it, selected a larger area and ran the code using Stamps 3.01. worked fine


#65

Hello, @ABraun thanks. i am now able to launch StaMPS. however i still have question, after processing the interferograms it didn’t launch matlab to process further.
is it because of the number of interferograms?


#66

2 interferograms (3 images) are not enough for PS InSAR. To get reliable results, time series of 20 images or more are reocommended.


#67

As answered by ABraun you must use images more the 20, or at least 4 interferograms (min # accepted by SNAP for StaMPS export).

Hello all.

After overcoming some errors reading manuals and forum posts, I managed to run StaMPS until step 4 where I have this error:

I can see in step 3 that it identifies “0 PS selected initially” and in step 4 “0 low D_A PS, 0 high D_A PS”.

¿Can anybody help me please?

Thanks.

check the Initial gamma threshold value. Its set as “1”, try by decreasing the value


#70

Thank you for you suggest @gomalhunzai ¿whare can i check that? ¿some script of StaMPS?


#71

After many mistakes and read a lot in the forum, I finish StaMPS (1,8) and export a kml file but i think is wrong. Now I need to do a processing with a stack of at least 20 images and read the manuals to interpret the interferograms.

Is there a way to export the results to Geotiff format?

thank you

Nice to see that the technical part works.
You might get better results with a larger stack of images. It would clearly improve the selection of suitable ps and the weeding of noise ect.
I would also recommend to run the steps separately:
stamps(1,1), stamps(2,2),… and check the printed messages, maybe adjusting the parameters which are relevant for the different steps (listed in the manual) with setparm(x,y)
I’m not a Matlab expert, maybe someone can comment on the GeoTiff question.

Thak you @ABraun i will process a stack with 20 images to obtain result better and i will experimet with parameters step by step.
