3D Geospatial Data Processing Group

3D Geospatial Data Processing (3DGeo) Research Group

3DGeo-Logo       IWR – Interdisciplinary Center for Scientific Computing      

We investigate and develop computational methods for the geographic analysis of 3D/4D point clouds. Our datasets are acquired by cutting-edge Earth observation technology (e.g. laser scanning/LiDAR, photogrammetry/SfM and SAR). We aim at increasing the understanding of geographic phenomena by observing and analyzing them in full 3D, in near real-time with high spatial and temporal resolution. Our methods can be applied to study physical processes (e.g. geomorphology), anthropogenic landscapes (e.g. emission reduction) and inherent human-environmental interactions (e.g. natural hazards, forestry and agriculture). Our research sites are spread all over the world: we perform in-situ 3D measurements, code in the lab and simulate Earth observation with our own open source software for virtual laser scanning.

Here, you can find our research projects, publications, videos, and open source code & data.

We love both programming and field work!

Open Data: Multi-platform point clouds and orthophotos of the inland dune in Sandhausen

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 […]

Improved Performance of HELIOS++ using High Performance Computing Techniques

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 […]

New(s) story about Sensing Mountains Summer School 2022

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 […]

New paper: Capturing complex star dune dynamics – repeated highly accurate surveys combining multitemporal 3D topographic measurements and local wind data

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 their […]

Continued multisource 3D point cloud acquisition at the AHK rock glacier

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 […]
