    Dear friends

    So far I could generate a displacement map from the Sentinel-1A SAR data with VV polarisation. However, what I need is the displacements along the LOS and Satellite along track. How can I extract such information from SARPROZ.

    Is there any way to combine different InSAR data, for example, ascending and descending tracks to optimally estimate the co-seismic displacements?

    Thank you all in advance.

    the displacement you detect from InSAR is along the LOS.
    To get displacement along track, you may use pixel tracking.
    We do not have yet a proper specific module for pixel tracking, but you can still perform it.
    Here an exercise showing how to apply pixel tracking (the third tutorial):
