Now it is totally clear to me. I appreciated all of your answers, thank you!

Thank you so much for the prompt reply. Now I understand where the problem is.

So does it also mean that, everytime if I change the graph e.g. from STAR to Full graph or MST, I should re-process the ASI for the current graph?

Dear Prof. Daniele，

I had asked in the forum that I coregistered and processed a long time series dataset including 280 images, and then I changed the “Dataset.txt” to process different subsets individually in one project. Here is the question link:Big dataset processing

The 3 subset is 2010-2012,2012-2014,2014-2016, and the whole dataset is fr…[Read more]

Thank you very much for your answer as quick as ever! I’ll follow the tutorial to do a test.
Sure, I’d like to take the course when our financial support could afford it. 🙂

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]

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

the result of linear model is added here

Thank you very much for your rapid and detailed answers!

1.

Cons: if your area is affected by temporal decorrelation/changes, keeping long temporal baselines will decrease the overall coherence.

For the cons you mentioned, I wonder if I individually corigester let’s say 50 images ; On the other hand, I select the same 50 images from the 280…

Please find the attached error files, thanks a lot !

Thank you very much! I’ll try as you recommended 🙂

Thank you for your rapid answer!

Hi,

it works after I delete the imgs in dataset.txt.

Thank you so much !

Best regards,

Thank you very much !

Thank you for your kind reply.

With respect to question 3, the “previous points” you pointed to are points selected by e.g. Amplitude dispersion index in APS?

Also, I have the confusion that, since QPS make use of DS points, shall I comprehend like this: The points selected with star graph are PS points, and points selected by other kind of…[Read more]
