    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.

    Dear Leewoneung,

    I am SARProZ team leader in Beijing and I think we have met begginning of this year for sw training.

    Then I want to confirm your question. Do you want help to check the reason why you got uplifting value in your result, right?

    From attaced screenshots I think the processing is not stable and reasonable but we need very detailed information to understand what you did. Do you have a detailed processing memo document then we can clearly understand and help you on that?

    Let me know. Otherwise you can also send email to me: liang@sarproz.com

    Cheres
