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!

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 [...]

3D Winter Wonderland – Multi-method acquisition for snow process research

A joint field campaign was conducted this week in the snow-covered black forest (Hundseck, 48.643°N, 8.228°E) by the research groups Hydrology and Climatology (Prof. Menzel) and 3DGeo (Prof. Höfle). Regular in-situ surveys are conducted at the site to investigate snow as crucial component of the hydrologic cycle, forest management, and evapotranspiration. Surveys comprise measurement of [...]

4D change analysis for improving our understanding of dynamic landscapes

Time series of topographic point clouds offer great possibilities to advance our understanding of dynamic landscapes. To exploit the full information these 4D datasets contain on spatial and temporal properties of natural surface changes, the 3DGeo research group is developing methods for 4D change analysis. These methods are required to answer fundamental questions on the [...]

Use of TanDEM-X and Sentinel products to derive gully activity maps in Kunene Region (Namibia) based on automatic iterative Random Forest approach

Gullies are landforms with specific patterns of shape, topography, hydrology, vegetation, and soil characteristics. Remote sensing products (TanDEM-X, Sentinel-1 and Sentinel-2) serve as inputs into an iterative algorithm, initialized using a micro-mapping simulation as training data, to map gullies in the [...]
