In this project we develop and combine cutting-edge remote sensing technology with snow depth distribution and RAMMS avalanche modelling. With this we want to improve the decision base for road safety in the Dischma valley in Davos.
Comprehensive satellite data, for smaller areas also drone images, with high resolution are well suited for the documentation of avalanche periods. For a (near-) realtime use the SLF is working on automating the mapping.
Information on large scale snow depths is still mainly based on interpolated point measurements. New developments in sensor – and software technology for digital photogrammetry in the last two decades offer new possibilities to derive high resolution, digital surface models (DSM) even over snow covered high-alpine regions.
