  • 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…

  • Open laser scanning data of trees – SYSSIFOSS project

    Our forest laser scanning dataset collected in the frame of the SYSSIFOSS project is now openly available through the PANGAEA Data Publisher: Weiser, H., Schäfer, J., Winiwarter, L., et al. (2021): Terrestrial, UAV-borne and airborne laser scanning point clouds of central European forest plots, Germany, with extracted individual trees and manual forest inventory measurements. PANGAEA,…

  • SYSSIFOSS at EGU21 on 26 April

    From 19 to 30 April 2021, European researchers from the Earth, planetary and space sciences are gathering in the virtual European Geosciences Union (EGU) assembly. On Monday, 26 April, two SYSSIFOSS presentations will be opening the block “Point clouds for forestry applications” in session BG11 – Remote sensing for forest applications. Dr. Fabian E. Fassnacht…

  • 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…

  • E-TRAINEE project: E-learning course on Time Series Analysis in Remote Sensing

    The E-TRAINEE project is a new collaboration project for developing an “E-learning course on Time Series Analysis in Remote Sensing for Understanding Human-Environment Interactions” with Markéta Potůčková (Department of Applied Geoinformatics and Cartography, Charles University Prague) as PI of the project and Heidelberg University, University of Innsbruck and University of Warsaw as project partners. The…

  • Disaggregating surface change mechanisms of a rock glacier

    How can multiple processes related to the deformation of an active rock glacier operating over different timescales be separated from each other? A preprint on the disaggregation of surface change mechanisms of a rock glacier has recently been published on Earth Surface Dynamics Discussions, an interactive open access journal of the European Geosciences Union. It…

  • 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…

  • 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…
