The software HELIOS++ simulates the laser scanning of a given virtual scene that can be composed of different spatial primitives and 3D meshes with distinct granularity. The high computational cost of this type of simulation software demands efficient computational solutions. Classical solutions based on GPU are not well suited when irregular geometries compose the scene [...]

The fourth edition of the Innsbruck Summer School of Alpine Research took place in September 2022, finally back in the lovely mountain landscape of the Ötztal valley in Tyrol, Austria. Once again, 40 participants - young researchers from all over the world - gathered in Obergurgl to learn and exchange about new concepts and solutions [...]

LiDAR data have become indispensable for research in archaeology and a variety of other topographic applications. To derive products (e.g. digital terrain or feature models, individual trees, buildings), the 3D LiDAR points representing the desired objects of interest within the acquired and georeferenced point cloud need to be identified. This process is known as [...]

While the impacts of global warming and current heat waves on glaciated areas have been in the focus of media reporting in recent weeks, also the dynamics of rock glaciers as part of the periglacial environment are strongly affected by changing climate. Rock glaciers are creep phenomena of mountain permafrost and an integral part of [...]

On Tuesday, 16 November 2021, Dr Katharina Anders defended her PhD research with great success.
In her dissertation, Katharina developed methods on 4D change analysis to extract natural surface changes from near-continuous LiDAR time series of dynamic landscapes.
Congratulations, Katharina, for this excellent research - we are very proud to have you in our team and wish [...]

For the first time, the inland dunes in Sandhausen (Baden-Württemberg, Germany) have been captured by UAV-borne photogrammetry and laser scanning. The dunes are a precious habitat for many specialized plants and animals. They formed during the last ice age by sand drift from the Rhine valley. The large inland dunes, originally stretching from Karlsruhe to [...]
