jaroslav started the topic Sentinel-1 co-registration image shift in the forum Sarproz Forum 7 years, 7 months ago
Hello!
It often happens, that Sentinel doesn’t take pictures of an exactly same place. One-two burst difference may take place.
I am wondering, if two pictures overlap covers area, that I’m interested in, what is the maximum allowed image shift, so that co-registration can be trusted? -
periz replied to the topic Life time index for point selection in the forum Sarproz Forum 7 years, 7 months ago
There are many things you don’t say,
as how you calculated those parameters, what does your dataset look like (in terms of number of images, distribution of acquisition dates/baselines/doppler). then we should check the original parameters as reflectivity, ampl stab ind, spat coher and so on.
anyway, as a general answer, if the spatial coherence…[Read more] -

Hello again
Thank You Doctor. I got it. But the Number of selected Points with spatial coherency index is less than ones with Amplitude stab. index.
In my case, most of the points have low spatial coherency.Result of selected Points using spatial coherency and amplitude stab. indices with the same threshold are attached here.

periz replied to the topic Life time index for point selection in the forum Sarproz Forum 7 years, 7 months ago
Hi Mahtab,
the life time is calculated from amplitude time series of good scatterers using this module http://sarproz.com/manual/amp_series_proc.html. The analysis is carried out on the amplitude series of single pixels.
The easiest way is to use the on-off model, then Tin and Tfin (birth and death dates) of targets will be estimated, their…[Read more] -

Hi Dr.Perissin
I want to select the Sparse Points based on their life time index, to use in the QPS technique. But when i choose the life time from parameters and press ‘Go’, no Sparse points are selected.
What should i do ?! in other words, Which parameter should be used for Points selection in the QPS technique ?!Thanks.

Hi Artem,
we are investigating it.
However, it looks like this is not going to generate errors. So, for the moment you can ignore it.

periz replied to the topic Invalid SRTM file in the forum Sarproz Forum 7 years, 7 months ago
Hi Jaroslav
sometime in December the SRTM ftp download changed the format and we uploaded the new code on Dec 12.
You have to update your software version. If you cannot use the “manage version” module, write an email to me, and I’ll send you a link

Thank You Periz for your important reply. Is any other way to come out from this problem ? By doing modification in Weather parameter.
Thank You

I confirm that the weather data download works.
If it does not on your side, unless you present an error, I am forced to think that it is a network problem between you and the weather database.
About the message you get at the beginning, it is due to a recent licensing issue. It is a temporary problem, do not pay attention to that message.

Hi Periz,
In this case, co-reg was successful hence no last error file generated. We can only see the log file where it mentioned rolling back.

Hi Kapil,
if you want to get assistance you must zip log and lasterror files and upload them here. Without those infos we cannot be of any help.
About the weather data download, it looks like a network problem on your side.
But again, we need log and lasterror.mat files (and you have to zip them before uploading) - Load More
