InSAR-derived Surface Deformation Map of Ordzhonikidze Rockglacier, Tien Shan, China

Strozzi, Tazio

The surface deformation map of Ordzhonikidze rockglacier in the Northern Tien Shan was derived from a ALOS-1 PALSAR-1 differential SAR interferogram. Surface deformation is in the satellite line-of-sight direction (incidence angle is about 35 degrees) and is restricted to areas where phase unwrapping could be succesfully performed.
