Spaceborne remote sensing for transport infrastructure monitoring: a case study of the Rochester Bridge, UK

This study presents a novel bridge monitoring approach for transport assets, based on the synergistic use of high- resolution (X-band) SAR imagery. A multi-temporal SAR Interferometry analysis is performed to detect potential issues related to the Rochester Bridge, located in Rochester, UK. A displacement map for the structure was produced using space-based SAR measurements acquired by the Italian constellation COSMO-SkyMed over the period 2017?2019, provided by the Italian Space Agency (ASI) in the framework of the Open-call for Science Project ?Motib ? ID742?. The outcomes of this study demonstrate that multi-temporal InSAR remote sensing techniques can be applied to complement information from non-destructive ground-based methods (e.g., ground-penetrating radars, laser scanners, accelerometers, etc.), paving the way for future integrated approaches in the smart monitoring of infrastructure assets.
