SARPROZ ©

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.

here is the log file.

Dear periz,

Thank you very much for the answer, I updated the software and the coregistration work successfully.But I didn’t find the log file for coregistration.

Also as I just complete the coregistration, although the matlab reports that the coregistration was concluded succesfully, I saw that for one image there is warning information. I put…[Read more]

hi Thibault,
to use Sarproz in matlab, you need the pcodes, which is a set of more than 1,500 files with extension .p, and which comes in a zipped file, pcodes.tar. If you have the main.exe file, instead, it means you have the compiled version that runs independently from Matlab. You cannot call main.exe from within Matlab.
Please send an email…[Read more]

Dear Bridget,
it is always useful to include the full log file in order for us to read more infos and better understand your case.
It seems to me that both issues should belong to an old software version, the last update should have solved them.
In any case, none of them represent a real problem for the success of the processing.
Please check you…[Read more]
