DORIS FP7-EU PROJECT: EXPLOITATION OF 20 YEARS DINSAR DATA ARCHIVE FOR LANDSLIDE MONITORING

摘要

Differential Synthetic Aperture Radar Interferometry(DInSAR) technique represents a valuable tool forremotely investigating ground deformation andproviding more insights on their spatial and temporalpatterns. In this work, developed within the frameworkof the DORIS FP7-EU project, we apply the advancedDInSAR approach referred to as Small BAseline Subset(SBAS) and fully exploit its capability to carry outmulti-scale and multi-sensor analyses of surfacedeformation. In particular, we use ERS-1/2 andENVISAT SAR data spanning the 1992-2010 timeinterval to detect and monitor landslides and subsidencephenomena occurring in the Umbria region, CentralItaly.
