Fault marking by InSAR Data and difference between SLC_1SSV and SLC_1SDV?

why does it end with .rar?

As for tutorials:

  1. Correct steps to form an interferogram: http://step.esa.int/docs/tutorials/S1TBX%20TOPSAR%20Interferometry%20with%20Sentinel-1%20Tutorial.pdf
    For Differential Interferometry, make sure you include the topographic phase removal in the inteferogram generation step.
  2. Unwrap the interferogram: https://media.asf.alaska.edu/uploads/pdf/current_data_recipe_pdfs/insar_phase_unwrapping_v5.pdf
  3. Convert to Displacement as described here: Subsidence map in 3d view
