Applications
- 10.7.1 InSAR Bridge Deformation — Using repeat-pass synthetic aperture radar interferometry to measure millimetre-scale vertical and horizontal deformation across bridge decks, piers and abutments.
- 10.7.2 Approach Road Settlement — Using satellite InSAR and optical change detection to measure millimetre-scale subsidence of bridge approach embankments before differential settlement causes structural failure or traffic accidents.
- 10.7.3 Pier Scour Risk Assessment — Using satellite-derived river morphology, flood-pulse tracking and InSAR subsidence data to quantify scour risk at bridge piers before a flood event strips the foundation.
- 10.7.4 Construction Defect Detection — Using very-high-resolution optical and SAR satellite imagery to identify surface anomalies, misalignments and material defects in bridge structures during and immediately after construction.
- 10.7.5 Asset Condition Trending — Using multi-temporal satellite SAR, optical and thermal data to build longitudinal condition indices for bridge assets and flag deteriorating structures before failure.
