High-precision assessment at the Aletsch glacier by remote sensing
The Aletsch glacier is receding. The flanks of the mountains are falling. The state geologist needs a cm-level assessment of the moving volumes. It’s a large, dangerous and inaccessible area. High-precision drone measurements on a regular basis are the only feasible tool to update orthomosaics and 3D models for change detection and volume calculation. With spatial analysis, we aim to quantify and anticipate the evolution of the area, in a genuine 4D situation.
