Surface Subsidence Map from TerraSAR-X InSAR, Distelhorn Rockglacier, Oberwallis (CH)

Strozzi, Tazio

Surface subsidence was derived from a time-series of TerraSAR-X differential SAR interferogram (InSAR) with a resolution of 5 m. Maps are available for the snow free seasons of 2009, 2012 and 2016. Surface subsidence is in the satellite line-of-sight direction (incidence angle is about 45 degrees) and is restricted to areas where phase unwrapping could be successfully performed.
