Satellite radar imagery is becoming more accessible, and at improving spatial and time resolutions. Interferometric Synthetic Aperture Radar (InSAR) has the capability to provide wide-area, high density, millimetre-level displacement measurements (obtained even in darkness and adverse weather conditions). This paper examines advances in InSAR satellite measurement technologies to understand their relevance, utilisation, and limitations for bridge monitoring. Waterloo Bridge is presented as a case study to explore how InSAR data sets can be combined with traditional measurement techniques including sensors installed on the bridge and automated total stations.
