@SUN-Ravenclaw If i well understand you have separated stacks of images paires and interfergrams.
You should export all your images+interferograms to the same directory : INSAR_20190208 that you create manually
On “Stamps Export” enter : Your_Working_Directory/INSAR_20190208
in the field “Target Folder” as shown bellow :
Use the same directory each time you will export a image+interferogram pair.
It would warn you that the directory exists already and it will be overwritten. Just ignore that and make YES. It will not overwrite the files but increment theme in each export
thank you for commenting.
Another solution is to create a stack of all image pairs (AB, AC, AD), both for the backscatter and the interferogram, and use these two stacks in the StaMPS export.
I checked the snap2stamps scripts again and this is how it is solved there, too. So you were right: The export has to be repeated for each pair, but the output folder is the same.
Hi Abdel, thank you for the answer above, I have completed steps 1 to 8 of StaMPS in matlab. However, I encountered some warning messages in step 6 (shown below). Warning: A’s rank is not sufficient to reach the computer precision range.
In lscov (line 200)
In uw_sb_unwrap_space_time (line 304)
In uw_3d (line 161)
In ps_unwrap (line 235)
In stamps (line 503)
Do you know why? Thanks again.
I found this tutorial in forum, with these steps, I may be misunderstood:
" 1) For S1, apply TOPS split and then apply precise orbit
2) Add all products to the Backgeocoding
3) Create Stack of Backgeocoded images (master_Stack)
Create a stack of Interferograms (Follow the step one of Prepare for STACK AVERAGING) on the resulting stack. { STEP 1 : master (SAME MASTER)+ (Different Slaves)first slave -> TOPS Corregistration, if necessary Deburst (and possibly subset), Interferogram, topographic phase removal, } master_Stack_ifg_dinsar .
Deburst both the Backgeocoded stack (master_Stack_Deb), and the Interferogram stack (master_Stack_Deb_ifg¬_dinsar .).
5) Add an elevation band to the Interferogram stack (by right-click > add elevation raster.).
6) Add the Debursted stack and Debursted Interferogram stack to the stamps export "
yes, sorry. You are right. It was a misunderstanding from my side yesterday.
Do you use the same master for all coregistered stacks?
By the way, to add elevation and lat/lon rasters can now be done in the interferogram generation step already. Unfortunately, there are many outdated instructions on StaMPS preparation in this forum. This one is the latest I know: Documentation on SNAP-StaMPS workflow
Yes, I use a 201912 image as master for each of coregistered stacks, I still don’t know whats wrong
thank you so much I’m gonna use this tutorial and check if I did sth by mistake
Hi again, I want to check with details the contents of folders PATCH 1… 2… of others people here! can somebody to list this please??? I am checking errors presented during the processing…
if you are free , could you please share some experiences about how to use Global Mapper and Surface to draw the pictures from data in StaMPS.
Thank you !
Hello,
It is about saving your results and drawing each of result as shaded relief map into the Surfer program. It takes a bit time according to your data. But first you need to plot your result into Global mapper and export the data as Surfer .grd data. These programs are easy to use but not free. If you find a way, I can assist you to plot your results as same as mine.

Hello again,
First of all, did you obtain result figures ? For example, mean_LOS velocity map? If you obtain that, you can export the values using matlab and you have LAT and LON values too. Then you need to creat LAT, LON, mean_LOS values respectively into the .dat file. If you make that tell me, afterwards it is time to use global mapper.

hello！i have got the graph you mentioned!but ,sorry ,i don’t know where and how to export the result!i have read the mannual again but couldn’t find.could you give me some hints?thank you!
