3D Geospatial Data Processing Group

3D Geospatial Data Processing (3DGeo) Research Group

3DGeo-Logo       HELIOS++     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!

Successful PhD defense of Katharina Anders

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 [...]

Uncovering the dynamics of the inland dunes in Sandhausen using UAV-borne 3D data acquisition

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 [...]

New paper: Opaque voxel-based tree models for virtual laser scanning in forestry applications

In the SYSSIFOSS project, we are investigating how we can take advantage of virtual laser scanning (VLS), the simulation of laser scanning in a computer environment, in forestry applications. These applications include survey planning and optimization, sensitivity analyses, and algorithm development. For example, VLS may be used to investigate the influence of different sensor and [...]

Multi-source 3D point cloud acquisition at the AHK rock glacier

Within the AHK-4D project, we continually monitor topographic change at the alpine rock glacier Äußeres Hochebenkar in Austria. Based on multitemporal and multi-source 3D point clouds at up to two-week acquisition intervals, we are developing methods to quantify the magnitudes and frequencies of individual processes of topographic change over varying timescales. This year, we have also [...]
