The 3rd edition of the international summer school “Close-range Sensing Techniques in Alpine terrain” took place in Obergurgl, Austria, in June 2019. A group of 40 young researchers (mainly PhD students) participated to learn about various sensors, processing techniques, and analysis methods for different topics in high-mountain research.
A recently published article [...]

Always been curious about how we develop our methods for 3D/4D change analysis?
Then check out our new video on high-resolution and high-frequency monitoring of a rock glacier in Austria!
Link to video

LiDAR datasets of the rock glacier provide the basis for the development of 3D and 4D methods for geomorphic change quantification within different research projects [...]

After three days of hard work in the field, Sunday was halftime workshop at HeidelErg. with diverse topics all around dunes, with and beyond the data collected in ErgChebbi.
Manuel Herzog introduced the first results from the geophysical measurements with regards to dune stratification. Ground penetrating radar in combination with Electrical Resistivity Tomography [...]

During the first three days of the field course in Erg Chebi, data collection focussed on the star dune with groups of students applying different techniques of geophysical and topographic surveying. Today, data was checked to plan the remaining three field days. A recap of this intermediate data revision will follow. For today, we’d like [...]

This week, the research groups Geomorphology and 3DGeo of the Institute of Geography at Heidelberg University are conducting a field course in the aeolian sand dune field Erg Chebbi in Morocco. The current field course is the second edition of “HeidelErg“.
The aim is to teach students different methods of data acquisition for physical geography, on [...]

New paper on “Multitemporal Terrestrial Laser Scanning Point Clouds for Thaw Subsidence Observation at Arctic Permafrost Monitoring Sites”
The paper investigates different methods for quantifying thaw subsidence using terrestrial laser scanning (TLS) point clouds. Thaw subsidence is a slow (mm‐cm per year) vertical displacement of the ground surface common in ice‐rich permafrost‐underlain landscapes. It is difficult [...]

How does a sandy beach naturally restore after a storm event? Invaluable information on this process is provided by a highly temporal (hourly) time series of 3D point cloud data acquired over several months at the beach of Kijkduin (NL). The permanent LiDAR system is operated by a team of TU Delft researchers in the [...]

Digital outcrop models provide a powerful data basis to obtain orientation information on rock masses. Robust and transferrable automatic methods are required to process and analyze these data, as outcrops and hence acquired 3D point clouds are influenced by varying conditions depending e.g., on the site, atmospheric conditions and other factors. A crucial aspect in [...]
