Railway Infrastructure Classification and Instability Identification Using Sentinel-1 SAR and Laser Scanning Data
Satellite radar interferometry (InSAR) techniques have been successfully applied for structural health monitoring of line-infrastructure such as railway. Limited by meter-level spatial resolution of Sentinel-1 satellite radar (SAR) imagery and meter-level geolocation precision, it is still challengi...
