Hello
I have a problem with aps test . after pressing the test button, the software is closed. I sent you the log . I will be thankful if you pay attention.
thank you

Hello Dear Friends,
The analysis of just 100 ascending data give a LOS displacement or vertical displacement automatically in SARPROZ. If It gives LOS, how Can I convert it into vertical displacement. -
periz replied to the topic Cannot configure sarproz mac matlab2020 in the forum Sarproz Forum 3 years, 11 months ago
the license for windows is different from the one for linux/mac
did you do this?:
1) open a terminal (2) type ‘hostname’ (3) ping the returned name (eg: ping mycomputername)
(4) if no packets are received, add the name returned by ‘hostname’ to the file /etc/hosts -

periz replied to the topic results from different model in APS in the forum Sarproz Forum 3 years, 11 months ago
the smart function is a non parametric model, basically a time filter that smooths residuals. thermal expansion is a function of temperature, which has a smooth component in time (like a sinusoid with 1 year period), but also higher frequencies fluctuations. the smart model would compensate only for the smooth component, while actual temperatures…[Read more]

Thank you so much for the rapid reply!
As for “estimate as well as possible the non linear model”, I wonder what’s the difference between using a non-linear model built by myself(e.g. include deformation induced by temperature or water level) and using the “smart” non-linear model?
Additionally, I know that I can use higher threshold for point…[Read more]

Additionaly, I suggest to use Graph Analysis and Refinement module. It is between APS and SPP button. There is possible to remove low coherence connections and improve APS graph.

Hi,
1. in the APS module the aim is estimating the APS, not the model parameters.
2. the APS is estimated from phase residuals. phase residuals = original phase – model. if the model is wrong, phase residuals will be wrong and the APS will be wrong.
If you have non linear signals, given the 2 above statements, you should either estimate as well as…[Read more] -

finally the linear model with thermal expansion is added.
By the way, the temporal coherence with index “_1” is the coherence before removing APS.
Looking forward to your reply. Thanks very much.
Best regards

Dear Prof. Daniele,
I have some questions when using APS for my dataset. I got 83 images from Jan 2017 to Dec 2018 covering a center city.
As the city has many buildings, and the images are dense in 2 years, I assume the deformation will be non-linear, and for buildings there will be thermal deformation. So I use 3 different models in APS…[Read more]

periz replied to the topic Main.exe stop working in the forum Sarproz Forum 3 years, 11 months ago
there is some conflict between your operating system/hardware/software configuration and the Matlab MCR. Write to support at sarproz dot come and ask for the Sarproz version compiled with matlab 2017. it might solve your issue

periz replied to the topic Reading interferograms using leggi in the forum Sarproz Forum 4 years ago
hi
you are trying to read a geocoded interferogram. geocoded data should be read with proper tools, as gis engines. or otherwise just import the geotif file in any coding environment, if u have geotif libraries.
leggi/scrivi are functions to be used in sarproz with sarproz-format data in SAR coordinates -
