bridgetwang started the topic non-linear deformation question in the forum Sarproz Forum 5 years, 8 months ago
Hello,
When I use the non-linear deformation processing, I got some questions even after reading the related discussions on the forum. Hope I can get your answers.
1、In sarproz, if “smart” is used, then linear deformation won’t be estimated. I want to know, is the linear deformation phase firstly removed from the interferometricc phase, and n…[Read more]

Hello,
I am a new Sarproz user and I am currently processing 7 Sentinel-1 images. When I press “Set orbits” in the “SLC Data processing” panel, I am not able to download Sentinel orbits since Friday (the days before the download was ok) and I get the following warning for all the images:Reading External Orbits
Cannot PING through FTP site for…[Read more]

As mentioned to you by email, you need to reproduce the error with the compiled version to allow debugging it

Each situation is specific, depending on the area, the data, the objective of the analysis.
I am not going to comment on your case, which would require analyzing many things.
A simple general statement: this website contains a decent amount of information about the QPS approach.
I am reporting here a single link, but there are many more:…[Read more] -

Hello,
I want to apply QPS on a mountainous area (attached MasterArea.kml) with 50 S-1 images. I selected dataset, applied preliminary analysis and preliminary geocoding. After all, at the APS processing step, I think something goes wrong.
Although I have tried APS with different values, connections are not coherent. Blue color intensity is…[Read more]

That’s excellent news!
Thank you for the reply once again.

We are just terminating a major update exactly to allow removing wide atmospheric effects and highlight local landslides. Wait maximum an other couple of weeks.

Greetings professor Perissin and SARPROZ team.
First and foremost I would like to thank you for your valuable assistance throughout the year.
In Western Greece (Ionian Sea) a substantial number of off-shore (near the coast) earthquakes have occurred of 5 to 5.5 magnitude and several farther from the coast of over 6 magnitude. As we process…[Read more] -
periz replied to the topic Aqcuire the APS removed stack in the forum Sarproz Forum 5 years, 9 months ago
You can plot the estimated APS from the APS module https://sarproz.com/manual/elabora_atmo.html
you can also plot the APS by selecting “choose a real file” in the “plot paramters” module and then browsing to the APS folder https://sarproz.com/manual/plot_par.html
You can also plot an interferogram by removing the estimated APS in the “Single…[Read more] -

Yes. Not all of them as they are over 3000 (full graph), but they look normal.

periz replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
Did you plot the interferograms?

janbu replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
Unfortunately, after creating the MT adaptive mask, I did process all the interferograms, selecting the “MT adapt” in the presets of the InSAR Params. Left everything else as default, processed the interferograms and created the coherence map with the results described.
Thanks -
periz replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
That module generates an MT adaptive mask, it does not calculate interferograms.
When you have the adaptive mask, you can use it to filter interferograms.
There is a preset in the InSAR processing options: “multi-temporal apdative”

janbu replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
Thank you. That was helpful.
I have proceeded with the MT adaptive filter, created the interferograms and generated the coherence map.
In order to get QPS (using the MT adaptive filter) I am assuming I would select points based on spatial coherence
When plotting the Spatial Coherence I basically get a map of all zero and in fact, no points can be…[Read more] -
periz replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
this is a case where the warning is actually useless, sorry for that
basically the writing function is set to launch a warning when NaNs are inputed (it can be indicative of some issues),
however, in this case NaNs are kept by construction at the borders of the image
you can proceed further, there should be no problem
