Good morning Yunus,
from my experience, at the moment I do the same, i.e. using the multi-sense module or external GIS-based tools to produce the maps of Vertical/EW motion with some spatial averaging.About the time series, what I do is to apply use the same formula used to derive the maps applied to some specific points, manually.

Hello scholars,
I am trying to calculate my ASC and DES data (tsobj) to E-W and V. I have tried to use multi-sens module and reached the result. whereas, the program said this module is under construction and I could not export the sparse data. anyone know how to do this with manual estimation from tsobj result data?Thank you in advance,

1. you miss telling what is your current software version
2. check the message above and download the servaddrs.mat file (do it once more if you already tried). place it in the Sarproz folder. try connecting again. please make sure you get a message saying that the servaddrs.mat file is used. if you do not get that message, you are doing something…[Read more] -

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

periz replied to the topic DEM generation in the forum Sarproz Forum 2 years, 9 months ago
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] -
markus-mueller started the topic DEM generation in the forum Sarproz Forum 2 years, 9 months ago
I would like to know if SARPROZ supports generation of DEMs using coherent SAR imagery. I had a look at the tutorials and the documentation, but could not find anything so far. Any help appreciated.

avelasco replied to the topic AD adaptive filtering with PS in the forum Sarproz Forum 2 years, 10 months ago
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]

Dear all,
on October 1st 2021 “let’s encrypt” (a widely used Certificate Authority) SSL/TLS old certificates expired, however, the ESA Copernicus website seems still using them. This is the reason why suddenly some Sarproz users experienced problems in downloading Sentinel orbital data from the Copernicus site.
We have provided a fix in the last…[Read more] -
periz replied to the topic APS Stratification meaning in the forum Sarproz Forum 2 years, 11 months ago
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 -
raingmaco started the topic APS Stratification meaning in the forum Sarproz Forum 2 years, 11 months ago
Hi,
I have some doubts about the stratification procedure for the APS estimation. More specifically, what is the meaning of MaxR and DSF. How SARPROZ estimates the vertical variation of the APS delay?
Thank you

periz replied to the topic AD adaptive filtering with PS in the forum Sarproz Forum 2 years, 11 months ago
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] -

Hello everyone!
What is the correct way to use Anderson-Darling Adaptive filter on the PSInSAR chain?
Is the following process chain correct:
1) Choosing AD statistical test in the Multi-Temporal Adaptive Mask.
2) Setting MT adapt. on the InSAR parameters.
3) Running Interferograms Processing. Sign convention in this step is opposite to SPP,…[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] - Load More
