Hi Daniele,
you wrote: “use the multi-look factors in the insar processing options.”
where these parameters is necessary to specify?

in the menu “InSAR Parameters Selection”, in a group “Interferometric Options”, “Multi-looking Rg-Az” http://sarproz.com/manual/insar_params.html,
or in the menu “Single Interferogram Processing”, in a group…[Read more]

Hi Jaroslav,

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

Daniele,
thanks for the answer!

Dananiele,
thanks for the answer!

Hi Artem,
you are right, the choice to give 2 (different) downsampling factors is not very useful there. In fact the software is already outputing square pixels in geographic coordinates (that’s the reason why if you give 2 different numbers, the bigger one is ignored). We will correct it in the future.
So, don’t worry about the shape of the…[Read more]

I’d be glad to, how can I contact you personally?

Jaroslav

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)

Hi Yuxiao,
I have updated the software, but problem still exists. Once I delete orbit files for some month, I will get errors for every image from deleted month. Broken orbits seem to be downloaded.
I can generate last error and log files for each case, if needed.

hi Jaroslav,
about geocoding improvement, up to this moment we used a matlab function in case of need (as you point out, when the GCP is precise, the geocoding is good enough)
this is the matlab function:
set_offscoreg(handles,OffsE,OffsN)
it shifts the data OffsE meters to the West (to East if OffsE is negative)
and OffsN meters to the…[Read more]

Hello,
Excuse me for late response. I have added missing log file.
Deleting the orbit file from ORBITS/S1A/MM didn’t help. Moreover, every image failed, if I had deleted its orbit file. I am also including last error file with log for error, that occurred after deleting an orbit file.

Hi Jaroslav,

your log there is empty and does not contains the corresponding error. Please paste the correct one so I can know exactly what happened.

Based on lasterror.mat, here is what I suspected: An orbit product was downloaded but corrupted somehow and ended in an error. To demonstrate if this is true: since you know the problematic image,…[Read more]

Again, I don’t understand.
Suggestion: let’s find some time for a remote session in which you show me what you do and we try to understand the case..

Hi dan,
Forget the above conundrum. All is solved now (but I do not how).
Anyway, the same set of sparse points at different size areas but with similar time series parameters behaves different. Is this normal. If yes, why?

No, the sequence is as follow: I closed multi-image insar, changed the area, processed time series again and then I had strange results. I decided to close all the modules (closing down SARPROZ), re-start it again, follow the normal procedure up to multi-image insar, include parameters, press go and then the glimse appears when press results.

Hi Felipe,
I am not sure I understood well.
Tell me if I am right:
– you are in the small area processing
– you processed insar time series (multi-image insar)
– you did not close the time series processing module
– you changed the area (with select area)
– you went back to the time series processing module
– there you got the error
If this is…[Read more]
