Hello all. I’m having a hard time running Stamps here. Can anyone tell me what’s wrong? Thanks
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
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?
2 interferograms (3 images) are not enough for PS InSAR. To get reliable results, time series of 20 images or more are reocommended.
As answered by ABraun you must use images more the 20, or at least 4 interferograms (min # accepted by SNAP for StaMPS export).
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?
check the Initial gamma threshold value. Its set as “1”, try by decreasing the value
Thank you for you suggest @gomalhunzai ¿whare can i check that? ¿some script of StaMPS?
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?
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
I’m not a Matlab expert, maybe someone can comment on the GeoTiff question.
