option nr 1: you create your custom grid at the beginning (initial mask) and you just keep it
option nr 2: to avoid possible wrong residual height estimation you force it to zero (geo localization is dependent on height)
option nr 3: you use the filter/matrix visualization feature in scatter plot and you output your result in geo coordinates

Hi,
Where is the ” phase2height and phase2flat constants generation (1.4.3.2 and 1.4.3.3)” step?

nothing is wrong. yours is the simplest and most straightforward approach for analyzing a small area.

Hello,
I am trying to process 32 Sentinel SAR images and to use PS-Interferometry on it. The area that I want to process is a small area (about 1km2) and I would like to know if I am following the correct procedure. These are the steps that I have followed after having loaded and co-registered my data:
– In the Site Processing panel I perform the…[Read more]

Thank you for this quick reply,
The message indeed was not the problem. I was able to continue the progress bar by pressing the up key (or probably any other key) in main.exe.

The message is not a problem. The coherence file is created after the coherence is saved. The coherence is the output of the mutli-temporal/time series analysis.
More attention deserves the progress bar. Please check if you get other kind of messages. It could be a network problem: try for a moment to stop anti-viruses or firewalls or similar and…[Read more]

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

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