Remote sensing of glacier flow, permafrost changes, and other cold region processes

We offer various projects using a range of optical and radar remote sensing methods such as classification, stereophotogrammetry, structure-from-motion, altimetry, or radar interferometry using ground-based, airborne or satellite-based remote sensing data.

Applications include local to global glacier change, glacier movement and instabilities (surges), glacier lakes, glacier avalanches, Arctic permafrost, mountain permafrost, etc.

Our study sites are globally distributed, for instance, Svalbard, Norway, Siberia, Alaska, Himalayas and Central Asia, North and South America, or New Zealand.

Most of our projects are in close collaboration with space agencies such as ESA, NASA, or the Norwegian Space Centre, or with geomatics and space industry, and we particularly exploit the most modern remote sensing instruments available.

Example project:

Glacier flow can be measured through image correlation from repeat spaceborne optical and radar images. The large number of archived satellite data suitable for such work enables the development of time series of glacier surface velocity fields with high temporal and spatial resolution. Such results support new insights into glacier flow and glacier response to climatic forcing.

Example project:

The new Structure-from-Motion technology allows for generating DEMs and deformation fields of unprecedented precision based on large numbers of overlapping repeat images. The technology can be used to obtain new insights in a range of geophysical processes, such as glacier change, landslide, slope instabilities, soil motion, tectonic movements, etc.
