The commune Sandhausen (Baden-Württemberg) got its name from the inland dune, which is located in the area of the village. In 2021 and 2022, the 3DGeo group of Heidelberg University conducted UAV-based and ground-based surveys of three areas of the inland dune of Sandhausen to acquire 3D point clouds and orthophotos. The dataset is freely and [...]

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 [...]

Morphologies of highly complex star dunes are the result of aeolian dynamics in past and present times. These dynamics reflect climatic conditions and associated forces like sediment availability and vegetation cover, as well as feedbacks with adjacent environments. However, an understanding of aeolian dynamics on star dune morphometries is still lacking sufficient detail, and [...]

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 [...]

New data description paper on our tree point cloud dataset was just published Today, our data description paper was published in the open access Journal Earth System Science Data: Weiser, H., Schäfer, J., Winiwarter, L., Krašovec, N., Fassnacht, F. E., and Höfle, B. (2022): Individual tree point clouds and tree measurements from multi-platform laser scanning [...]

From 5 June - 11 June 2022 the ISPRS Congress took place in Nice, France. The 3DGeo research group had three paper contributions which can now be found online: (1) Virtual Laser Scanning of Dynamic Scenes Created From Real 4D Topographic Point Cloud Data. Find all details in the video (link) and paper and check the related [...]

A new data article on “A high-resolution 4D terrestrial laser scan dataset of the Kijkduin beach-dune system, The Netherlands” was just published in Scientific Data. Along with the fully openly available dataset, the article presents insights into the importance of frequent and spatially detailed surface measurements - and what to do with them. Get directly to [...]
