Urban deformation monitoring using Sentinel-1 SAR data: a case study

Abstract

This paper describes the monitoring of the deformation associated to the construction works of a tunnel. The deformation is monitored using a Persistent Scatterer Interferometry technique and Sentinel-1 SAR data. A particular implementation of a PSI technique is described, which makes use of stable areas in the vicinity of the study area. The monitoring results include maps of accumulated deformation, to spatially describe the deformation, and deformation time series to describe the temporal evolution of deformation over the measured points
