Video on research of 3DGeo on change analysis methods at an active rock glacier
Always been curious about how we develop our methods for 3D/4D change analysis? Then check out our new video on high-resolution and high-frequency monitoring of a rock glacier in Austria! Link to video LiDAR datasets of the rock glacier provide the basis for the development of 3D and 4D methods for geomorphic change quantification within…

Student field trip to Northern England
From 2nd – 9th March 2020, students of our department took part in an excursion to Northern England. Among the areas visited under the lead of Dr. Jack Williams were the Peak and Lake Districts, the North York Moors National Parks and Durham County. Preliminary seminars provided the students with background knowledge on the topics…

Leaf-off UAV-borne laser scanning
Members of the 3DGeo research group were recently taking advantage of the good weather to acquire some more data within the DFG-funded project SYSSIFOSS. We packed the drone and the RIEGL miniVUX-1UAV laser scanner, and drove to the forest near Bretten where 8 of our plots are located. In four days and 16 flights we…

GIScience Heidelberg at Annual Meeting of DGPF
Last week, members of GIScience Heidelberg participated in the 40th annual meeting of the DGPF (German association for photogrammetry and remote sensing) in Stuttgart, Germany. Presentations were contributed by PhD students Lukas Winiwarter and Katharina Anders (3DGeo Research Group), as well as former GIScience fellow Jun-Prof. Dr. René Westerholt. Read up on the presented topics…

Treeathlon – 3D tree mapathon
On Tuesday, 25.02.2020, the 3DGeo group and the SYSSIFOSS project partner from KIT organised a collaborative data processing event. 24 participants spent 6 hours (10:00-16:00) extracting individual trees from airborne LiDAR forest point clouds. In the SYSSIFOSS project, the segmented 3D tree models are required to simulate 3D forest stands when combined with a forest…

New project: LOKI – Airborne Observation of Critical Infrastructures
On Feb 12, 2020, the kick-off meeting for the newly funded BMBF project LOKI – Airborne Observation of Critical Infrastructures (Luftgestützte Observation Kritischer Infrastrukturen) was hosted by the GIScience and 3DGeo research groups of Heidelberg University. The aim of the LOKI project is to develop an interdisciplinary system that enables fast and reliable airborne situation…

SYSSIFOSS project @ 2nd symposium on satellite-based earth observation in Cologne
On November 12-13, Jannika Schäfer from KIT presented the SYSSIFOSS project at the 2nd symposium on satellite-based earth obersvation (2. Symposium zur angewandten Satellitenerdbeoachtung) in Cologne. SYSSIFOSS is a joint project between the Institute of Geography and Geoecology (IFGG) of the Karlsruhe Institute of Technology (KIT) and the 3DGeo Research Group of Heidelberg University. In…

The Importance of Monitoring Interval for Rockfall Magnitude‐Frequency Estimation
Rockfalls commonly exhibit power law volume-frequency distributions, where fewer large events are observed relative to more numerous small events. Within most inventories, the smallest rockfalls are the most difficult to detect and so may not be adequately represented. A primary challenge occurs when neighboring events within a single monitoring interval are recorded as one, producing…

Using OSM data to generate scenes for LiDAR simulations in HELIOS
A new tutorial for the 3DGeo‘s LiDAR simulation software HELIOS has been posted to the repository’s wiki page. It shows a simple way to generate scenes of real landscapes including building and vegetation models as well as terrain from NASA JPL’s SRTM data. When applied to OSM data in the city of Vienna, the obtained…

Classification of 3D ALS Point Clouds using End-To-End Deep Learning
In a new publication, we show how deep neural networks can be used in an end-to-end manner for the classification of 3D point clouds from airborne laser scan data. The research, based on the award-winning diploma thesis of Lukas Winiwarter at TU Wien, has now been published in “PFG – Photogrammetrie, Fernerkundung, Geoinformation“, the Journal…
