Hello friends,

I followed the tutorial by Mr. Yuxiao very closely. Results seem much better than before, but there are still a couple of anomalies.

First, the resulting points from 0.85 thresh amp. stab:

Hi Steffan,
sorry for the late answer. We need to find some time to check your data. We need to see things from the beginning.
For the moment, I can suggest you to check this simple exercise https://www.sarproz.com/yuxiaos-tutorials/
(the last tutorial). It gives you an idea of the results you should see step by step

After reprocessing the point of interest with 135 images, the results are the same (extremes of displacement).

Here are examples:

Here are APS parameters:

Maybe this time series can provide some insight:

Thank you!

Thank you Yuxiao

Yes you can ignore.

The warning message there should be quite self-explanatory.

Dear periz,

I am reprocessing the dataset with 135 images (from 60 previous), I will post the results soon.

Thank you

This bug is solved.

Hello,

I have downloaded the newest version of Sarproz, and I am working on 48 images of Sentinel 1a data.
Frist, I would like to say that in previous version of SarPROZ I didn’t have this issue and everything worked perfectly (same datasets).

During Slaves extraction, I receive this error “Image N does not cover your AOI! Check footprints of N…[Read more]

Yes it works !
Thanks, professor.
Sorry for the late reply

Yes, there is surely something wrong.
We should check the APS results

In all geocoding functions you have a menu and you can choose among kml, geotiff RGB, geotiff 32
The last option exports the actual values and you can load them into a GIS software

And here a similar answer with more options:…[Read more]

the displacement you detect from InSAR is along the LOS.
To get displacement along track, you may use pixel tracking.
We do not have yet a proper specific module for pixel tracking, but you can still perform it.
Here an exercise showing how to apply pixel tracking (the third tutorial):

Hello ogokce,

A new version of sarproz is available and please try to give it a test. The bug should be gone.

Hello ogokce,

I believe what you are seeing there is a bug as we are working on some new updates in the change detection module. We will work on that and let you know when the bug is fixed. Meanwhile, I am glad to hear that you can still use the other way around to solve it.

I will keep you updated.

Yours,
yuxiao

Update: As it was described in the tutorial, I used “load mask” and “visualization tools – Scatter Plots”. It solved my problem when I changed x axis to longitude, y axis to lattitude and press GeoOut. There might be a bug in change detection menu but this “visualization tools – Scatter Plots” tool saves the day. Thanks…
