Landslide detection using sentinel-1 LSC


#1

Please i need your advice. I am working on landslide detection using using sentinel-1 tops SLC data over an AOI. I have downloaded two data of before and after of the events. i have followed the training video of RUS HAZA 05 but my interferogram appear blue and coherence blank.
Are data from sentinel-1 data hub needs any further processing before i can apply the steps in the video?

Thank you.

in case you performed topographic phase removal during the interferogram generation, please try it again with SRTM 1Sec Auto Download (instead of 3Sec which has download problems lately).
