BBD-V: A National, Transport-focused Ground Motion Monitoring Service in Germany

Transport infrastructure is vulnerable to ground motion caused by natural or anthropogenic processes. Monitoring ground motion from space through multi-temporal interferometric synthetic aperture radar (MT-InSAR) is less resource-intense than traditional methods. It allows for an increased data comparability on large spatial extent, the transferability of approaches between different linear transportation infrastructure - roads, rail-, and waterways - and processing consistency across Germany. The BBD-V ( germ. Bodenbewegungsdienst für den Verkehrssektor) is a currently developed transport-focused and Sentinel-1 MT-InSAR-based ground motion service for Germany. By tailoring monitoring to the transport sector, it aims at increasing the applicability of the approach to linear infrastructure in terms of usage, process adaptation, and user-targeted communication of results.
