I am trying to cover the entire SAR image processing in nine days by using the European Space Agency's SNAP software https://step.esa.int/main/download/sn... . This video covers Interferometric SAR or InSAR. It shows how to create DEM from SAR data.
InSAR application requires SNAPHU plugin. Please refer the following video to install SNAPHU plugin:    • How to install SNAPHU plugin in SNAP ...  
Data used in this demonstration can be downloaded from: https://ietrlab.univrennes1.fr/pols...

Please go to my Playlist (   / @basudebbhatta2691  ) to get the videos in organized manner.
