Thank you for your reply Dr. Perissin. Could you please explain more about the steps to get the raw interferometric phase values (just topographically corrected) using the PSI method in Matlab (my data is the time series of sentinel-1 images). I had already done the PSI method in the compiled version of SARProz, but I am confused about how to…[Read more]

good that you found the solution. however, I do not suggest you to use the ampl xcorr as default. we’ll try to find out a way to use it only in case of failures.

I solved the problem myself.
the problem was in coregistration.Firstly I used “only orbits” mode for coregistration.
After analyse of Site.log the program had gave warning to that in coregistration has some thing wrong.I tried “Ampl Xcorr” mode for coregistration and it worked match better. No warnings, No Stripe
So in future I use “Ampl…[Read more]

I generated an interfereogram from two Sentinel-1 phase images. In the interefereogram (Burst_line.png) has clearly seen stright lines that match bursts stich lines. I would like to fix it. What are the tools in SarProz to fix this kind of problem. I use compiled version.
Thanks for answer

You may set in module “Insar params” appropriate settings
Do not filter and multilook interferograms check “Flattening” and “DEM remove”
save settings
genereate interfereograms in module “interferograms protsessing” -

Thank you for your reply.
I need to do topographic correction before extracting phase values. The phases should mostly contain atmospheric and displacement phases. How should I do topographic correction in Matlab?

hi,
1. if you want to work on data in the way you describe, you should use matlab.
2. to read data in sarproz (in matlab), you can use the “leggi” function https://www.sarproz.com/groups/sarproz-group/forum/topic/aps-processing-4/
3. using “leggi” you can directly read the original images and perform all what you need without caring about APS…[Read more] -

Dear Dr. Perissin,
I am using the multi-temporal analysis module of SARProz (compiled version). I need raw phase values (before atmospheric correction) for my research. I assume that atmospheric correction is an unavoidable step in the multi-temporal analysis, and I can not skip it. The strategy that has come to my mind to get raw phase values…[Read more]

n-ghasemian replied to the topic Sentinel-1 incidence angle in the forum Sarproz Forum 4 years, 3 months ago
Hello everybody,
I read the explanations above about the two functions get_baseline and geo2incang. My problem is that I am using the compiled version of sarproz. Could anyone give me a detialed explanation about how to use these functions to extract the incidence angles for each PS or any other pixel in the compiled version of sarproz?
Thank you

Hello
I use of Sarproz to find the ground displacement, to recognize the mechanism of cracking in a badland ground. I downloaded a series of sentinel 1 A data from 2014 to 2016 (7 picture ). I process them with Sarproz. 3 interferogram was ordinary. but, 3 of them was discontinuous.
Also, when I want to make mask points, the software couldn’t find…[Read more] -

Hi. I am looking for free SLC data (not registered or co-registered) to download for infrastructure monitoring using PS-InSAR (or other) technique. Who are some data distributors that provide free and quick access to these images to process in SARPROZ? I am particularly interested in the TerraSAR-X, COSMOS, and Sentinel-1 Missions data.
Thank you.

periz replied to the topic Loading reference point in the APS module using command line mode in the forum Sarproz Forum 4 years, 5 months ago
Hi Dominika,
First of all, at the moment we did not think about letting the user pass a manual reference point in the APS module in the command line mode. The sw will load the RefPoint.mat file (the default way it is usually saved), if it is working in update mode. Otherwise, it’s the sw to choose the default ref point. The reason is because in…[Read more] -

Dear Sarproz Team,
I came across an issue with the command line mode.
I first analysed my AOI manually. In the APS module, I loaded RefPoint_1134_65.mat file, which I created earlier, as the reference point. The message in MATLAB confirmed that the reference was loaded correctly. Then, I went to the MISP module, where again I loaded the same…[Read more]
