Spatial Resolution and density of points are important

[Zara Yad]

Hello ,

I started to learn how to use Mintpy for InSAR time series analysis, in my application the spatial resolution and density of selected points are very important, my AOIs are also quite small, it can be as small as few ten square meters, I have three questions, could you please help me to find the answers?

1) are multi-looked interferograms needed for this small-baseline approach? if no, how could be the precision of estimated displacement for detected DS points and also density of the points in this method compare to PS InSAR?

2) what is the minimum size of an area that can be processed? in this page Interpreting ISCE2 + MintPy results / the way to calculate accumulate of displacement ,  can see that the minimum size of area to be processed by ISCE2 is a S1 burst, so in this case, Is this true that SNAP might be a better option to prepare interferograms in smaller area?

Thanks,

Zara
