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?
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): https://www.sarproz.com/yuxiaos-tutorials/
