Monitoring of Large Scale Landslides using High-Frequency and Multi Orbital Satellite SAR Sensor

Abstract

In this paper, an example of displacement monitoring of landslides using interferometric SAR analysis is reported. The displacement of the mountain landslides was separated into vertical displacement and east-west displacement by 2.5-dimensional analysis using ALOS-2 with multi-temporal and multi-orbital data. The direction and the boundary of displacement were consistent with the results of displacement measured by airborne laser profiler between 4 years and also with the field survey.
