Geodetic Measurements for Environmental Research
The analysis of geodetic measurements in combination with geotechnical and meteorological sensors at periodic intervals or over longer time periods provide insights that are related to climate change.
Scanning of Swiss Rock Glacier
Unlike ordinary glaciers, rock glaciers are not extensive bodies of ice but mixtures of rock debris and ice that flow down valleys at speeds of 0.1 to 1 m (0.3 – 3.3 ft) per year. They are typical in alpine or high mountain permafrost regions and direct conclusions about climate change can be drawn from their movement. Investigating the movement dynamics of rock glaciers presents a great challenge to all the various earth science disciplines involved. Students at the University of Applied Sciences Northwestern Switzerland (FHNW) have taken on this challenge with the help of a Leica HDS4400 long-range scanner. more
