    I try to use SARPROZ for decomposition deformations in LOS to deformations in E-W and UP-DOWN. I have two dataset – ascending and descending (data from Sentinel-1A, Sentinel-1B).

    I did the following:
    1. I have exported time series in “Sparse Points processing” (for ASC and DSC data). I have exported time series like .tsobj files.
    2. I have imported both .tsobj files in “Multi-sensor analysis”.

    My problem is that final exported KML-s for LOS Velocity, Vertical Velocity and E-W Velocity are exactly the same.

    I tried to export by “Time Series Module” but results are the same.

    I attach printscreens from processing.

    Please, can you help me?

    Did you do process the 2 clouds of points?
    1- estimation of relative shifts (offsets)
    2- estimation of AD pairs
    here a brief description
    After having estimated those 2 things, you can plot vertical and horizontal components either on AD pairs or on a grid (not on the original points)
    in the future we will add more options for the grid
    also the time series resampling is not implemented yet

    Yes, I tried both, estimation of relative shifts (offsets) and estimation of AD pairs. And I used AD pairs and grid but also in this case are my outputs the smame.

    your case needs to be checked in person.
    if you did not solve it with ur colleagues, we need to find some time to look into it remotely
