InSAR Remote Sensing for Performance Monitoring of Transportation Infrastructure at the Network Level

The main objective of this project is to provide a framework for the consistent and reliable delivery of information about subsidence/sinkhole formation, bridge settlement, slope stability and pavement distortion to state departments of transportation (DOTs) in the form of geographic information system (GIS) layers that can be seamlessly integrated within existing decision support systems. The goal of the project is to help DOTs with the optimization of resource allocation for maintenance and inspection of the transportation infrastructure at the network level. The project pushes the use of novel spaceborne radar technology (Interferometric Synthetic Aperture Radar – InSAR) from the validation to the network level implementation stage by packaging the analysis tools, developed during RITARS-11-H-UVA, into deployable ArcGIS toolboxes. This allows for the development of a comprehensive remote-sensing-based inspection framework for the early detection of ground deformations which might be precursors of potential hazardous situations within the transportation corridor.
