Sentinel-1 SAR Amplitude Imagery for Rapid Landslide Detection

Alessandro Mondini, Michele Santangelo, Margherita Rocchetti, Enrica Rossetto, Andrea Manconi, Oriol Monserrat
2019 Remote Sensing  
Results show that in about eighty-four percent of the cases, changes caused by landslides on SAR amplitudes are unambiguous, whereas only in about thirteen percent of the cases there is no evidence.  ...  On the other hand, the signal does not allow for a systematic use to produce inventories because only in 8 cases, a delineation of the landslide borders (i.e., mapping) can be manually attempted.  ...  Acknowledgments: We thank the anonymous reviewers for their careful reading of our manuscript and their insightful comments and suggestions.  ...
