Integrated Use of Space-Born Data for SHM of an Ancient Infrastructure

Abstract

AbstractThe use of space-born data for monitoring single structures or infrastructures and detecting structural anomalies is recently becoming more widespread. The increasing application of satellite data in the field of Structural Health Monitoring (SHM) is due to the significant advantages that they should bring compared to the traditional monitoring techniques. In fact, satellite data can allow us to obtain information quickly not only on the structure of interest but even on the surrounding area. Satellite data can provide different kind of information based on their nature: interferometric satellite data can detect displacements with high accuracy; while other satellite data are able to provide geophysical information on the soil state (i.e., soil temperature, soil moisture, etc.). However, the interferometric data are generally applied separately from the other types of satellite data that are less used, so there is no combination at the moment in the SHM field. In this paper, an integrated use of different space-born data is proposed to understand if their cross-comparison can provide a more comprehensive overview of the structural behavior of a structure or infrastructure. As a benchmark, satellite data are applied to an ancient aqueduct, which is used to verify the proposed methods.KeywordsStructural Health MonitoringSatellite dataEnvironmental dataArchitectural heritageRemote sensing
