cnu_lee replied to the topic Linear trend threshold in the forum Sarproz Forum 8 years, 7 months ago
–“why are you surprised that the result is within the imposed range?”
Based on the velocity results and “linear trend” threshold setting, I found the velocity result is within the range of “linear trend”. In fact, the threshold of “linear trend” was estimated by person,it’s just a estimated value, so it wasn’t correct,and it didn’t…[Read more]

why are you surprised that the result is within the imposed range?
the range is used exactly for the purpose to limit the result within a minimum and a maximum.
the result can be different in case of noisy data (the algorithm has a random component, and random data can lead to random results)anyway, never use a-symmetric ranges in the APS…[Read more]

hi,Pro. Daniele,
I have one question about APS estiamtion “linear trend” threshold.I found if I set “linear trend” between -90 and 5. The deformation velocity result is in this range. But if I set the threshold between -120 and 5, the result will be in this range.
So how to decide the accuracy of the result?

Hi Amir,
this means that you are missing the matlab parallel processing toolbox.
You should contact your IT person for that. I can anyway send you the compiled version and you can keep both versions on your computer (the license is the same). You can use the compiled one for running the operations requiring functions not installed in your matlab…[Read more] -

Hi all. I am facing with an error when running the co-registration step. The error is undefined function ‘Composite’ for input arguments of type ‘double’. Here, I also attached the .log and .mat files for your kind help.
Best regards,

hi Shimin,
you should reduce the jpg image and paste it here again, so that we can see the error. Also, if you got a lasterror.mat include it together with the log (zip them before attaching them here).
In the meanwhile, to get an update write to support at sarproz dot com, specifying whether you are using the pcodes version, compiled for win or…[Read more] -

Dear sir,
The version I used now can’t read TDM data in it. So I want to update sarproz to solve it. But I’ve some problems that I can’t update it online.I think I need you help to solve this problem. Or can you give the lastest version? I can insatll it by myself. Thank you very much!…[Read more] -
periz replied to the topic Using GAMMA .rslc in the forum Sarproz Forum 8 years, 8 months ago
The coregistration refinement may be needed if you are working with high resolution, high normal baselines, important topography.
We had clear evidence of that with Cosmo datasets in mountainous areas.
Your errors look a bit strange and in fact may be due to the 2015b version of matlab

Hi Dan,
I’ll have to look into re-ordering the SLCs. In the meantime I’m running the refinement with GAMMA and I’ll then import the files again. But do you think this is a good approach if I ultimately want to run PS?
I have attached the zipped up error files.
Best,

periz replied to the topic Using GAMMA .rslc in the forum Sarproz Forum 8 years, 8 months ago
Hi Jackie,
unfortunately at this moment the coregistration refinement works only with images coregistered by Sarproz. The reason is that the algorithm is using the results of the first coregistration.
Would that be possible for you to access SLC images? it would also be a chance to compare the result with yours.
We could also implement a…[Read more] -

Dear Daniele,
I have CSK raw data which I focused with GAMMA and I “roughly” coregistered them. I have successfully imported the resulting .rslc into sarproz, and the mean amplitude looks good. But I would like to perform the coregistration refinement using the external DEM now, is this possible or do I have to do it previously in GAMMA? (asking…[Read more] -

Hi Dear Ivana,
Thanks for the testing, this is indeed a bug and I’ve fixed it.
I’ll submit the fixed code for sarproz.
Between now and the publishing of new version, as a temporarily work around, this bug can generally be avoided by not selecting areas close to the border of Sentinel image.
Also in your log I see that you have sentinel…[Read more]

Hello,
I am attaching an error I encountered more times (but sometimes not; in different areas), I am processing an area close to image border; what is the problem here and how shall I avoid it?
If I understand it well, it concerns the number of bursts…?
Thank you, Ivana

periz replied to the topic amplitude values in the forum Sarproz Forum 8 years, 8 months ago
Hi Ivana,
you raised a good point. We used to store the normalization constants many years ago, but we did not implement it when we included the SLC module. The image amplitude is normalized to have an average value equal to 1. You could further equalize the images using only stable targets. But the matter of fact is that at this moment the…[Read more]
