Monitoring Topographic Changes in a Periglacial High-mountain Face using High-resolution DTMs, Monte Rosa East Face, Italian Alps
This paper describes a remote sensing-based approach for detailed topographic investigations in steep periglacial high-mountain faces. The study was conducted at one of the highest periglacial rock faces in the European Alps, the permafrost-affected and partially glacierised east face of Monte Rosa....
