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]

Tannia,

also, please be aware that memory stays for RAM which is a different concept from disk space.

Hello Daniele,

could you please let us know the relation between original image intensity (in the SLCs) and the values got in “refl. map”?

I need to compute sigma_0 and know how to do it from original SLC but these values are different.

Thank you very much, Ivana

Hi Tannia,

Generally speaking, colored buttons (including red and green) means those steps that are essential for generating interferograms and doing multi-temporal analysis. Green means you’ve executed the step and an output is saved locally. Red means the step isn’t executed/completed yet.

It is worth mentioning that, in sparse point…[Read more]

Hello,

Well, I followed Timon’s instructions. The main processing window I have red alert in interferograms and coherence, which is the next step? In roi_pac first I used to execute coherence.

Any advice is welcome, thanks!

Hello,

After executing again Sparse Points Multi-Image Processing, I saved all outputs included “APS” in final Fine APS,
and the laptoo was out of memory. Then, I had a message in matlab to execute the command HELP MEMORY, and now again I have space in disk, what does it mean?

I don’t understand, but now “sparse points processing is green”.…[Read more]

Hi Dan,

Thanks by answer. However, still I had red alert in the bottom “Sparse Point Processing”. I’m processing again this option and trying to get a workstation to continue working in my job.

Hi Tannia,
this is a temporary licensing problem. We have noticed that this may happen if the computer is particularly overloaded and as a consequence almost stuck.
However, it’s not affecting the processing.
Also, notice that the log file you sent is empty and the lasterror.mat file has a different date. In other words, no errors occurred.

Hi Jackie,

it’s a bit a complex matter, there are many things to discuss.

first of all, in the APS it makes no sense to give asymmetric ranges in the parameters estimation. You are processing connections and you have no idea whether you are going to process A-B or B-A.
secondly, again because you are processing connections, you may want to…[Read more]

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
