  • 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…

  • 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…

  • Behavioural Effects of Spatially Structured Scoring Systems in Location-Based Serious Games – A Case Study in the Context of OpenStreetMap

    Location-based games have become popular in recent years, with Pokémon Go and Ingress being two very prominent examples. Some location-based games, known as Serious Games, go beyond entertainment and serve additional purposes such as data collection. Such games are also found in the OpenStreetMap context and playfully enrich the project’s geodatabase. Examples include Kort and…

  • 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…

  • HELIOS used in a study on hetero-integration which enables fast switching time-of-flight sensors for light detection and ranging

    The Heidelberg LiDAR Operations Simulator (HELIOS) is an open source laser scanning simulation framework for interactive simulation and visualization of terrestrial, mobile and airborne laser scanning surveys. It can be flexibly used for teaching and training of laser scanning, development of new scanner hardware and scanning methods, or generation of artificial scan data sets to…

  • 2nd International Workshop Point Cloud Processing

    From 4-5 December 2019, the 2nd International Workshop Point Cloud Processing was co-organized by euroSDR, the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF) and the Institute for Photogrammetry (ifp) at the University of Stuttgart. The aim of the workshop was to present and discuss the processing and evaluation of point clouds focusing on…

  • Graduate Celebration 2019

    On 29 November 2019, we celebrated together with the graduates of 2018/2019 of Bachelor and Master of Science in Geography, and also School Education (Lehramt) at the ceremony in the venue of the Neue Aula of Heidelberg University. Moreover, Prof. Carl Zillich gave an interesting talk about perspectives, controversies and visions of the International Building…

  • 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…

  • Follow-up BMBF/MOST project “ER3DS” meeting at National Cheng Kung University in Taiwan

    Within the BMBF-funded project ER3DS (Emission Reduction in Smart Cities Using 3D Spatial Sensing and Analysis) a second workshop and exchange visit was organized and hosted by the National Cheng Kung University (NCKU) in Tainan, Taiwan, from 16 September to 19 September 2019. The first day included two lectures at the Dept. of Geomatics (Prof.…
