| Abstract | Since 2014, the National Research Council Canada (NRC) has led partnerships in which the application of radar satellite imagery for bridge deformation monitoring has been validated in five major case studies (including the North Channel Bridge in Cornwall (ON), the Jacques-Cartier, Victoria and Samuel de Champlain bridges in Montreal (QC), and the Confederation Bridge leading to Prince Edward Island (PEI).
Based on the knowledge and experience developed in these bridge case studies, a set of technical guidelines is summarized and presented in this paper, which discusses the characteristics of bridges and the satellite parameters that can affect and improve the quality of satellite-based bridge deformation monitoring. The overarching goal of these guidelines is to enable more efficient and accurate monitoring of bridges using radar satellite imagery by recognizing the limitations of the technology and by better understanding which bridge and satellite parameters can optimize its application. |
