SAR Interferometry Data Exploitation for Infrastructure Monitoring Using GIS Application

Monitoring structural stability in urban areas and infrastructure networks is emerging as one of the dominant socio-economic issues for population security. The problem accentuated by age because increasing risks due to material deterioration loss load capacity. In this case, SAR satellite data are crucial identify assess deteriorating conditions civil infrastructures. large amount available from sensors leads exploitation development new GIS-based procedures rapid responses decision making. recent decades, DInSAR technique has been used efficiently monitoring structures, providing measurement points located on structures with millimeter precision. Our study analyzed behavior settlements, attempting discuss interactions soil examining different types such roads buildings. method based long-term interferometry a semi-automatic procedure measure displacement (mm/year) through application performed “Implemented MOnitoring DIsplacement” I.MODI platform. analysis provides extensive information spatial temporal continuity up 25 years record, using multi-sensors ERS, Envisat, COSMO-SkyMed. interpretation uses time series analysis, supported orthophotos, layers DBTR (regional topographic database), Digital Surface model (DSM), hydrogeological map show anomalous high rate observe correlation settlements sediments. With Geographic Information System (GIS), we were able relevant parameters, velocity advance direction slope (deformation profiles), cumulative displacement, trend changes structures. results illustrate an innovative that allows management facilitate effective which protocol was developed at scales, integrating into GIS.
