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!

The impact of recent gully filling practices on wheat yield at the Campiña landscape in Southern Spain

The significance of gully filling practices on agricultural production has been only rarely evaluated in literature. In this study, a medium-sized catchment was selected, for being representative of the conventional farming practices on annual crops in the Campiña landscape in Southern Spain. During two wheat campaigns, an analysis of the spatial and temporal evolution of [...]

Talk: Deep Learning for Point Cloud Processing

Lukas Winiwarter of the 3DGeo group was invited by the Austrian Society of Surveying and Geoinformation (OVG) to give a talk on the application of deep learning on point clouds, which took place on March 24. In his talk, Lukas presented four different state-of-the-art approaches to consider the irregular, unordered structure of point clouds, which [...]

Open Data + Open Software - A perfect match

On 1st March 2021, the Swiss Federal Office of Topography (SwissTopo) released all official geodata according to the principles of “Open Government Data (OGD)”. With this step, Swisstopo is making large volumes of high quality geodata freely accessible. We are most excited about the 3D data, which includes digital surface models, digital terrain models and [...]

Hells Bells - interactive 3D view of underwater speleothems

In collaboration with the Institute of Earth Sciences at Heidelberg University, the 3DGeo group reconstructed underwater speleothems in a cave in Yucatán, Mexico. The so-called “Hells Bells” are fascinating formations in several sinkholes, at the boundary layer between fresh- and saltwater. The full 3D mesh model obtained from several thousand photographs taken by a [...]

Fully automatic spatiotemporal segmentation of 3D LiDAR time series for the extraction of natural surface changes

When and where do changes occur in dynamic natural landscapes? A new method has been published that enables the automatic extraction of surface changes from entire time series of 3D point clouds. The developed method of spatiotemporal segmentation extracts changes regarding their surface change history, which makes it particularly useful for natural scenes that are [...]
