Hi V,

For the data corruption part, it is a known issue. In sarproz we implemented several ways to detect corruption of SLC images. You should get warnings/errors if they are corrupted.

In the case where no warnings/errors were given, it is always helpful to check:

(1) The JPGs of SLCs in EXT/yyyymmdd folders and in FITTED folders. If the…[Read more]

Hi Jaroslav,

Yes and No. A few explanations:

Yes Part:
1. My experience is that spatial baseline is not a big problem for tops in general. Since (a) tops has such good control in its orbits precision & accuracy; (b) the baseline is usually quite small (within 200 meters in general). So geometric decorrelation is not really a big issue here.…[Read more]

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

Q

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.

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.

when you download your Sentinel SLCs, create your own directory for data, like, “TEST”, then inside this folder create a new one called “SLC”, and put either all the .zip files of Sentinel inside, or the zipped folders, ended in “.SAFE” inside the SLC folder. then read the “TEST” folder in sarproz.

Hi Ali,

After we updated the Sentinel TOPS code recently, we didn’t include the stripmap part. Thus in the current version, the stripmap is not supported.

I will have this implemented very soon. I am a bit busy the coming week, but I will have Sentinel stripmap function ready to be used by the first week of May.

I will have this implemented very soon – but I apologize here – It is approaching my finals as my semester is ending in two weeks. I am getting extremely busy this week preparing for my…[Read more]

Hi Jaroslav,

Please send me the following file:

In your EXT folder, go to the master image folder, you will find the file named yyyymmdd_PP.meta.mat (PP is polarization, VV or VH in typical).

Send it to me qyuxiao@sarproz.com and I can take from there.

Hi PY,

I am actually aware of this situation in some of the scene. I will investigate into your case and come up with the solution.

I will let you know how it goes.

Thanks Nemati.

I will still benefit from your SLC file list to improve the software.

Q

Hi N,

Could you please also kindly pass me the list of SLC files for my debug purpose?

Thanks!

Q

I will need some time to replicate the problem and found out what is going on,

Hi YaLe,

send me the list of SLC filenames, I need to run your data and browse through all the problems.

Hi Jaroslav,

Send me an email to qyuxiao@sarproz.com and let’s discuss the things. Thanks!

Do you have time to let me remote control to your PC and have a look? (probably via teamviewer, or any other that you would like)
