Well, apart from the fact of questions… why only 5 interferograms?
If you only have few images, you could try to apply the double-differences technique. For doing so, you need to pick up a reference point near by the subsidence area so the atmosphere could be neglected and assume that is the same than for the selected reference point.
please describe your problem a bit clearer. What data are you using and why are you not happy with the results? You can include screenshots to illustrate it.
hey @virk_rana,
Can you please tell me how you are saying that the given values (-0.076 and +0.028) are in km? Can we change them to cm or mm in the map only?
Hi @ABraun ,
When I processed the Sentinel images using the PSI method in MATLAB, is the amount of displacement( ps_plot (v_do ) obtained different from the amount of displacement shown using the CSV export in QGIS? Which is the actual displacement value. I’m really confused.
QGIS has its own way of color stretching. These values do not represent the total min/max values.

Thanks for your very helpful answer@ABraun,
This means I have to open the csv file in Qgis and check the minimum and maximum, it will be the actual amount of velocity? Right?
