Workflow between SNAP and StaMPS

zhuhaxixiong · June 29, 2019, 4:06am

when i use viStamps to disaplay the result(linux),the unwrap phaset shows:
![](file:///C:\Users\leslie\Documents\Tencent Files\951755015\Image\C2C\NMUMR4ZSNB[%P[[X%`@Y@R.jpg) ![](file:///C:\Users\leslie\Documents\Tencent Files\951755015\Image\C2C\`ANO)D4P%6O0KG8Y)MOU@E4.jpg) but the deformation shows: ![](file:///C:\Users\leslie\Documents\Tencent Files\951755015\Image\C2C\S(GBYBMTNW]@VCSYDYSS1Y3.png) ![](file:///C:\Users\leslie\Documents\Tencent Files\951755015\Image\C2C\(DNMDPAAM)F0N[I_M0Q)8R.jpg)
my deformation map is a strip,and be differerce from the manual of vistamps, and dont have a map layer

Sorry but I have never used viStaMPS.
Maybe anybody can give any hint?

My only guess it that you had not provided latitude and longitude information.

thank you，and i have try to vilisualizer the result by Stamps Visualizer (successfully) and iVstamps (failed),when i export the all the points to csv ,then load csv by R studio,it is really bad the page refresh very slowly because of the data volume,i wander how i can i control the step when export to csv file like export to a kml file

Well… not sure but indeed viStaMPS has nothing to do with the workflow between SNAP and StaMPS…

So I would suggest the proper forum fhreads that address the different issues.

Good luck with viStaMPS.
Still StaMPS has own commands to convert output to kml files: ps_gescatter

thanks for your reply

Dear mdelgado
i meet a mistake when i creat stack in snap:
after creat a stack of 22 S1 data, i check each intensity image in the stack and found that one(20150924) of the intesity image shows black ,what is happened to this situation?and when i do apply orbit file , all data 's orbit can be found in C:\Users\leslie.snap\auxdata\Orbits directory except the 20150924.so i think the black image was caused by failed to apply the orbit file in this data(20150924),but all of these steps in snap did not have a error message,what should i do?

Dear @Gijs,
Did you find a solution to solve this problem?

Gijs · August 30, 2019, 8:52am

Hey Jennifer,

The problem seemed to be caused by an incorrect ifg, when i reprocessed the issue was solved. you can check this by checking the mean amplitude and ammount of 0s printed out at the mt_prep_snap phase.
In my case i had accidentally left an ascending aquisition in my descending folder or something like that.

Greetings,
Gijs

Jennifer · August 30, 2019, 8:58am

Thank you…will check such in my case…

Jennifer · September 4, 2019, 8:10am

What you mean by this? Whal should i check in mean amplitude and the amount of zeroes? I get some values… but what you mean by checking it? Can u tell me precisely please…

Jennifer · September 4, 2019, 9:14am

i get this error…
Could anybody tell me a feasible solution?

@Gijs just now i figured that one of my interferogram is blank with no values and all zeroes… Thank you

Gijs · September 9, 2019, 11:42am

This is exactly what i said in the post above.
You had to check the print output given when you run mt_prep_snap.
but you posted the print ouput from StaMPS (1,1) print output.
Glad you found the problem either way, i was on vacation.

Greetings,
Gijs

Dear @andretheronsa @ABraun,

I have the same problem as you described here, in step 1 of StaMPS loading data into Matlab:

Did you find a solution for it? Could it be related to my StaMPS_CONFIG.bash, which I am not sure if I parametrised correctly?

I changed the last line according to the explanations given by @thho but I am not sure if this is the case for me.

I source StaMPS_CONFIG.bash, navigate to the folder containing the StaMPS input in the terminal and than start matlab. getparm() also works.

I am using:

Ubuntu 18.04 LTS
StaMPS 4.1 beta
Matlab R2019a update 3

I would appreciate your helpt very much!

ABraun · September 10, 2019, 9:30am

I can’t remember how I got rid of this error, but I remember that it was not the CONFIG file but rather related to the stamps scripts.
Did you use the distribution from here: https://github.com/dbekaert/StaMPS

verenahg · September 10, 2019, 9:35am

Hello @ABraun,
yes I am 90% sure I did. Could it help to reinstall it?
Thanks.

ABraun · September 10, 2019, 9:43am

it is worth a try.
From your screenshot I see that you haven’t defined a triangle and snaphu directory. If the executables are in the bin folder, everything is fine. I just wanted to go sure because this would cause problems in later steps of StaMPS.

Are you running on a windows machine by chance? I remember that I had this on a windows computer only.

verenahg · September 10, 2019, 1:37pm

Hi. No, I am using linux. I tried to reinstall StaMPS (unzipping the folder, navigate to the StaMPS/src folder, make, make install. Do I miss something?) but the error is still occuring.

Any further ideas? Thank you for your help.

ABraun · September 10, 2019, 1:39pm

if I recall correctly, the problem was already caused in the mt_prep_snap part before matlab was started.
But I have no idea how to check if the interferogram are generated correctly there.

Did you repeat this step as well after reinstalling StaMPS? (removing the old folder before, of course)
