Multiscale landslide susceptibility assessment
As per Loan Number 1062, this project set out to generate Digital Elevation Models (DEM) of a landslide-prone slope to calculate volumetric change using the Riegl VZ-1000 long range scanner. The scanner was deployed at Glen Ogle, Stirlingshire on 4 occasions: October 2016, May 2017, September 2017 and April 2018. The Riegl VZ-1000 scanner was used to provide high-resolution data coverage of topography over a broad (3 km x 1 km) spatial scale. Error surfaces were categorised in the field by noting the ground cover and associating a code within the RtK check points. The capabilities and limitations of long range TLS for long-term monitoring and precise modelling of slope failures were investigated to analyse whether a multi-method approach could be implemented to generate surface models of sufficient consistency to identify the development of slope instability.
