if you have a very good dataset, many images, regular time sampling, good normal baselines dispersion, stable and robust estimation, then go directly with the non-linear model.
if your dataset is not ideal, not many images, not so robust and so on, go with the linear model. then only if you notice problems, you can run a non-linear estimation,…[Read more]

Thank you so much for your kindly answers. Now I know clearly that SarProz will give linear+nonlinear estimation at the same time when smart is choosen.

I have a further question here: For most cases, I have no prior knowledge of whether the deformation is linear or not. Then should I choose linear model first or nonlinear model first?

As I…[Read more]

1. the atmosphere here has nothing to do. if you use the smart function, the linear phase won’t be removed. However, you still have the option to remove it, by choosing “read” on the corresponding line. Clearly, to read it from the disk, you must have previously processed and saved it.
2. if the non-linear model is obtained with a low pass filter,…[Read more]

you need to update the software

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:

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

Hello professor
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.

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]

that’s something we need to check looking at your data then

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

Did you plot the interferograms?

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
