Hi milan,

can you post the filename of the images you’re using and the area you’re extracting (center, samples and lines) along with your log file and lasterror so I can take a look?

Thanks!

Yuxiao is going to answer you soon.

My only comment is: are you using the most recent Sarproz version?

Using the “single interferogram processing” module you can implement all options you like…
process the interferogram, plot it, geocode it
use it to make all experiments you like

Ivana,
+/- 3*sigma is an operation that has nothing to do with this quantity.
As previously stated, this quantity is not calibrated and it should be simply considered as a measure of the curvature (how wide) is the peak. But again, the value is not much meaningful by itself alone, it’s useful when compared with that of an other target.
Nobody ever…[Read more]

Hi Daniele,

thank you very much for the explanation and also for the implementation.

Can you also please let me know how is the periodogram peak width defined? If e.g. the width of 90% of the peak coherence. Just to consider if really plus minus three sigma_vel are the “limits” of the velocity estimation as the values really look quite…[Read more]

The basic ideas of Sarproz were firstly conceived during my phd thesis in the years 2003-2005 (check my thesis on Amazon or the urban target recognition paper). At that time I was using ERS and I calibrated the dataset with some corner reflectors. Since then, the calibration constant has been left in the code, and it is used when you process…[Read more]

Thank you very much

The master is chosen in the barycenter of the distribution of normal/temporal baselines.
If you are mixing multiple polarizations, the sw will take a master among images at the highest resolution.
Registration is carried out by cross-correlating patches of images.
Then a polynomial model is fitted in the estimated shifts considering their…[Read more]

Thank you Yuxiao,

but today (with the 06-Oct version) I get a similar/same error.

(will try the other stuff later. Before, I threw the images with only partial overlap away, but now I do not. The area of interest is covered, but I get these problems…)

Regards,
Ivana

To conclude this thread, the newest version of sarproz should solve this issue.

Thanks!

Hi Ivana,

We’ve uploaded a new version of pcodes that solves this issue.

By the way, I have tested the new version of pcodes on your testing site, and it should also solve the previous problems you’ve mentioned in the other thread.

Please let me know!

Thanks,

Yuxiao

i see that pcodes version that I used is 7-Sep-2015, so i’ll try it with new one from 26-Sep
