Time series of topographic point clouds offer great possibilities to advance our understanding of dynamic landscapes. To exploit the full information these 4D datasets contain on spatial and temporal properties of natural surface changes, the 3DGeo research group is developing methods for 4D change analysis. These methods are required to answer fundamental questions on the [...]

Gullies are landforms with specific patterns of shape, topography, hydrology, vegetation, and soil characteristics. Remote sensing products (TanDEM-X, Sentinel-1 and Sentinel-2) serve as inputs into an iterative algorithm, initialized using a micro-mapping simulation as training data, to map gullies in the [...]

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 [...]

As part of the practical field training “Physiogeographische Geodatenerfassung” this week, a group of students acquired the gravel bar and terrace at an oxbow of the old Neckar river near Ilvesheim (49°28′36″ N 8°34′34″ E) with geophysical and 3D surveying techniques.
In small groups, the students learned a different surveying strategy and processing the acquired data [...]

How can multiple processes related to the deformation of an active rock glacier operating over different timescales be separated from each other?
A preprint on the disaggregation of surface change mechanisms of a rock glacier has recently been published on Earth Surface Dynamics Discussions, an interactive open access journal of the European Geosciences Union. It [...]
