Potential of an Automatic Grounding Zone Characterization using wrapped InSAR Phase

Abstract

The work deals with the identification and the characteriza-tion of the grounding zone area using InSAR data. The ideais to point towards a methodology that minimizes the role ofthe operator and provides results with performance that canbe mathematically described using input parameters. The ap-proach uses the information of the interferometric phase gra-dient to follow the path of the grounding zone and fit themusing a physical model that describes the ice bending. Theapproach is tested on more than 300 km grounding zone com-paring also the results with existing products.
