Technology 02 Sustainable Digital Twin

Efficient bridge health monitoring

using satellite SAR* and AI

* SAR: Synthetic Aperture Radar

Periodic health monitoring from the sky of bridges that are difficult to visually inspect close-up

Early detection of serious damage that can lead to collapse

• Exhaustively capture and intuitively visualize pre-collapse damages in bridges built during the past high economic growth period
