LANDSLIDE INVENTORY AND MONITORING USING SENTINEL-1 SAR IMAGERY

An important application of differential SAR interferometry (DInSAR) and Persistent Scatterer Interferometry is landslide detection and monitoring. Several studies have been published, which make use of the entire spectrum of SAR data types available in the last 25 years. This paper describes a procedure to update landslide inventory maps using Sentinel-1 data. The paper briefly discusses the main advantages of the Sentinel-1 SAR data. Then it describes the data analysis procedure used to update landslide inventory maps using interferometric data and a number of additional information layers. The effectiveness of the procedure is illustrated by the results of a study area located in the Molise region, in Southern Italy.Grant numbers : This work has been partially funded by the Spanish Ministry of Economy and Competitiveness through the project MIDES (Ref: CGL2013-43000-P)
