InSAR techniques and applications for monitoring landslides and subsidence
Interferometric synthetic aperture radar (InSAR) methods and applications for mapping and monitoring displacements on mountain slopes and subsidence in urban areas were investigated in the EC project MUSCL (Monitoring Urban Subsidence, Cavities and Landslides by means of remote sensing) using various techniques. The area-extended differential InSAR technique was applied for mapping slow slope m...

15 صفحه اولRemote Monitoring of a Landslide Using an Integration of Gb-insar and Lidar Techniques
Landslide monitoring activities are of paramount importance for landslide hazard and risk assessment. They allow predictions to be made of the phenomenon evolution which can be used to define risk scenarios, especially when urban areas and infrastructures are involved. Over the last decades, spaceborne and, more recently, ground-based interferometric synthetic aperture radar (GB-InSAR) have bee...
متن کاملRailway track inspection using GPR
Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...
متن کاملIntegrating geomorphological mapping , trenching , InSAR and GPR for the 1
13 This contribution illustrates the advantages of integrating conventional 14 geomorphological methods with InSAR, ground penetrating radar and trenching for 15 sinkhole mapping and characterization in a mantled evaporite karst area, where a 16 significant proportion of the karstic depressions have been obliterated by artificial fills. 17 The main practical aim of the investigation was to eluc...
