SARPROZ ©

Hello Prof Periz
Where we can download last version of SARPROZ. I can not update my sarproze. when I want to update, the below err appeared.

An ERROR occurred and was saved in the file lasterror.mat, directory C:SARPROZE
The LOG FILE can be found here 09_Nov_2021_12_41_36_sarproz.log, directory C:SARPROZE
Please read carefully the document…[Read more]

Thanks Daniele, will send you an email.

Hi Markus,
sure you can generate DEMs in Sarproz. There are many ways for that, depending on the characteristics of the data you want to use. That’s one of the reasons why we did not publish a clear procedure. There are other reasons for that, but the discussion would be a bit long. You can anyway find some material online. We published papers…[Read more]

Hello periz,

Thanks for the detailed response.

When applying spatial filtering, in InSAR parameters, should be selected “Output Coherence = post-filtering”? So that this post-filtered Coherence was used on MISP module as Weights. I would appreciate it if you clarify this doubt.

Regarding AutoMISP-PRJ-Atmo.mat file, the image shows APS for 5…[Read more]

The stratification in Sarproz is estimated as the APS component correlated with the topography.
If you flag that option, Sarproz will estimate a coefficient and build a model based on the external DEM and on the estimated coefficient. That model will become part of the APS estimated and removed from interferograms.
We advise you to use it only in…[Read more]

DSF is DownSamplingFactor
Because APS is low frequency signal then the APS results will be multilooked in that factor

Hi,

1. the so-called PS approach is based on the following concept:
A. star-images graph (single master).
B. no spatial filter (full resolution images, no need to generate interferograms).
C. no weights (the phase of each image weighs the same).
In such context, in Sarproz you do not need to generate interferograms. follow the tutorials online to…[Read more]

1. the coherence trend in time becomes visible when you plot the coherence as a function of time. this plot is generated when you display the final test, after APS estimation and removal. the first plot that you show is a histogram, there is no time variable there
2. the histogram you show is not bad. it shows 2 peaks: signal and noise. now you…[Read more]

Hello

I have a question about the output of KMZ. I work with 52 sentinel-1 images between 2017-2018. After APS estimation, in time series modules, I have used the sparse TS geocoding part to export the def trends of PSs to KMZ. But, the export of KMZ for each ps is between 2099-2599. I have tested the procedures several times, but I can not find…[Read more]

By the way, I also want to ask under these situation, how do we choose Non-Linear Weighting parameters. I usually use the default parameters(0.71 0.84 0.97).

Thanks for the update. I used to have lots of problem with older version while I switched to Matlab 2019 or newer versions. But the new version, so far was awsome.
