Permanent scatterers are selected in the PS-InSAR process

Why create a TIN with a selected permanent scatterers?

I think it seems that the TIN does not calculate the surface displacements between the Permanent scatterers through interpolation.

And what is the strength of the TIN ?

What is the difference depending on the strength of the TIN?

By setting the smart value to 5 and executing the time series module, the settlement value of PS-InSAR was obtained as the excel data.
However, there are many differences from the last value of the time series and the cumulative displacement.
I know that cumulative displacement analyzes the first and last images using a specific module.
I used 21…[Read more]

I worked PSInSAR Process.
First I had choosed spatial coherence > 0.7 and I completed a series of preliminary works.
And I choosed 1-Sigma/mu Index ,So I completed a series of PSInSAR works.
I Wanted to Decrease Values That are displacement. but I getted Increase Values.
My Study area is railway so I think that place should be subsidence.

I unchecked Linear processing when I did ‘time series processing’ and ‘Sparse point processing’ too.
and then I tried cumulative displacement,
but I couldn’t get the cumulative displacement when ‘LOAD MASK’ step.
Only “0” when I checked cumulative displacement in Load mask.
How can I get the cumulative displacment??

I can’t select cumulative displacement at Load mask.
If I select cumulative displacement, I have only 0 selected points.
before the select cumulative displacement at Load mask, I seleceted Amp. Stab. Index 1-Sigma/Mu, and Temporal coherence. and I finished APS estimation and Sparse Points Processing. I checked Linear Trend and Height estimate at…[Read more]

at time series module, I want to polygon or raster style map.
but scatter map is only point map, and resampling map is No blank(The No data is calculated with a value of zero, I don’t want it, I wanna just blank)

I want to make the maps likes Beijing Cumulative Displacement detected by two parallel TSX tracks and Los Angeles Cumulative…[Read more]
