sorry, I can’t grant to keep track of every step. What about the comments on your questions in other topics?
There are answers to almost any question in this forum:
- general workflow: Interferogram Formation - Subtract topographic phase check box
- full tutorial on subsidence monitoring: https://eo-college.org/resources/insar_deformation/
- notes on image selection and constraints: How can we calculate the volume of displaced material with displacement band(displacement_VV)?
- atmospheric disturbance: Subsidence Map
- InSAR - A practical approach: Have a look the comment on landslides in chapter 4.1.4
Because of the constraints (topography, surface change, atmosphere, long temporal baseline), many studies favor PS InSAR for landslide analysis:
