Onderzoek naar toepassingsmogelijkheden INSAR data voor bruggen
The municipality of Amsterdam has approximately 2,000 bridges, of which they actively monitor 850 with leveling. This is a costly and labor-intensive procedure that produces infrequent measurements of only a part of their assets. Furthermore, the municipality of Amsterdam – as many other asset managers - assesses and prioritizes their bridges by using existing data like state of maintenance, type of construction and leveling information. A sophistication step can be made by using remote sensing measurement data like InSAR.
InSAR is a technology that has the potential to facilitate this process by providing measurements with a high spatial and temporal density in a cost efficient way and can make it easier to identify the most critical bridges in the municipality at any time. The challenge is therefore to investigate how InSAR can be used, possibly in combination with leveling, as input for risk prediction models and maintenance planning.
