The primary objective of this project is the application of remote sensing methods to investigate geological and geotechnical problems and to assess the hazard and risk of natural hazards in the context of infrastructure and climate change. For that reason pre-existing and new methods and tools are improved and developed for selected case studies. Furthermore, remote sensing technologies (e.g. multi-temporal aerial photography, satellite imaging, photogrammetry, laser scanning, radarinterferometry) offer a proven means to detect and monitor endangered and inaccessible areas in an area-wide manner. The field of application of remote sensing is widespread and comprises the generation of high resolution digital terrain models, spatial mapping of geological structures, geotechnical rock mass classification, determination of volume changes, and monitoring of slope deformations.
