On the integration of multi-temporal synthetic aperture radar interferometry products and historical surveys data for buildings structural monitoring

Abstract The management and the safeguard of existing buildings infrastructures are actual tasks for structural engineering. Non-invasive monitoring techniques can provide useful information supporting process safety evaluation, reducing at once impact disturbances on structure’s functionality. This paper focuses exploitation advanced multi-temporal differential synthetic aperture radar interferometry (DInSAR) products infrastructures, subjected to different external actions. In this framework, a methodological approach is proposed, based integration DInSAR measurements with historical sources, accurate 3D modelling consistent positioning reflecting targets in GIS environment. Documentary sources prove particularly helpful collecting technical information, reconstruct an geometry building under monitoring, limiting in-situ surveys. analysis DInSAR-based displacements time series mean deformation velocity values allows identification possible critical situations be monitored. presents approaches, increasing accuracy levels, study active deformative processes examined related damage assessment. An insight into these interpretative approaches given through application proposed procedure two case studies city Rome (Italy), residential named Torri Stellari Valco San Paolo (1951–1953) housing complex referred as Corviale (1967–1983), by exploiting whole COSMO-SkyMed data archive (both ascending descending acquisitions), collected during 2011–2019 interval. Pros cons various deeply discussed, together estimation required computational effort.
