Hi Venera,

First of all, please make sure you are using the newest version.

Second, it would be helpful to check the coherence of the pair that shows this warning. The goal is to check that if the coherence of interferogram is indeed so bad that accurate subpixel coregistration could not be performed.

At last, it would be helpful if you pass…[Read more]

Hi
I look forward to your reply and i’ll appreciate your fast response,
Thank you in advanced
Best regards

Thanks for the quick response.

Hello,
I didn’t actually completely overcome this issue yet.
However, the master choice seems to help sometimes. In cases of problematic co-registration I usually try to manually evaluate image list in order to exclude the most noisy ones and choose the most contrast image as a master.
Somebody, correct me if I’m wrong, please.

Hi Jaroslav,
How did you overcome your issue?
I am facing these warnings, however I am processing a whole subswath..

Thanks.

Hi,

I am still working on it, please give another couple of days. Thanks.

Q

I’m still waiting for the sarproz update to processing stripmap data of Sentinel sensor. I’ve been using version 5-may-2017 recently, i’ll be thankfulness if you notice me whenever new sarproz update arrives, which has the capability of process​ing stripmap sentinel data, and give me new pcodes file.

hi
Thanks very much for your helpful tips.

you can download srtm from this websit.

Hi Periz
How can i download SRTM manually and place them in that folder?

Thanks

Hi Pawel,
we could change that piece of code to allow you using that function with your old matlab version.
However, you may find other issues later on. If it is easy for you to upgrade matlab, please do it. If you cannot, let us know and we will make those changes
best

If you are using MATLAB R2011a or previous version I would suggest switching to R2012a or later.

I will leave this to Dan for adding comments.

Those are not errors
they are informative messages.
If in your area no SRTM files are available, there is nothing wrong. If SRTM should be available, then the software cannot download them for some reasons. Do it manually and place them in that folder

Hi Wang,

First of all, thank you for taking a carefully look at the log before processing the data to the next step.

Sentinel uses a method called spectral diversity (SD) for coregistration in order to meet the strict restriction of Sentinel TOPS coregistration. To give a simple explanation it uses the spectrum of TOPS for coregistration.
