Abstract:The goal of the project was the implementation of interferometric synthetic aperture radar (InSAR) monitoring techniques to allow for early detection of geohazard, potentially affecting the transportation infrastructure, as well as the monitoring of current status at the network level. The InSAR datasets collected by TRE provided rich information with extremely accurate sub-centimeter data about the history of the displacement over two areas. For the first area (AOI1), located near Staunton in central Virginia, the dataset covered a period of almost four years allowing for a very accurate analysis of the temporal behavior of the observed displacements. A second area (AOI2) including Northern Virginia and a section of Washington, DC was included to extend the analysis to a region with high urban density and highways with extreme traffic volume.
