  • Press release: Understanding the Spatial and Temporal Dimensions of Landscape Dynamics

    The research of the 3DGeo group is featured in a press release about Understanding the Spatial and Temporal Dimensions of Landscape Dynamics. The text illustrates how Heidelberg geoinformation scientists develop new computer-based method to analyse topographic changes. The described method is published in this article: Anders, K., Winiwarter, L., Mara, H., Lindenbergh, R., Vos, S.…

  • 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…

  • Auto3Dscapes video about research in 4D change analysis

    This new video by the 3DGeo group presents the challenges of 3D Earth observation and our advances in 4D change analysis in the frame of the Auto3Dscapes project: Direct link to the video: https://youtu.be/Fdwq-Cp0mFY Many thanks to Claudia Denis and David Jäger for helping to realize the video! We are also very happy about the…

  • Digital Teaching Award featured in Magazine of Heidelberg University

    The digital teaching prize by Heidelberg University that was awarded to two members of our institute is featured in a current special edition of the university’s magazine UNISPIEGEL: Find the full article on “Adjustment to digital formats” (translation by the author) on page 2 of the magazine here (in German). Information on the awardees Dr.…

  • 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…

  • Geodata acquisition for physiogeographic analyses at a gravel bar

    As part of the practical field training “Physiogeographische Geodatenerfassung” this week, a group of students acquired the gravel bar and terrace at an oxbow of the old Neckar river near Ilvesheim (49°28’36” N 8°34’34” E) with geophysical and 3D surveying techniques. In small groups, the students learned a different surveying strategy and processing the acquired…

  • 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…

  • Concluding field work in the dunes around Erg Chebbi

    The last days of field work in Erg Chebbi continued at the star dune to wrap up final tasks: filling gaps in the data, adding some dune arms to the ground penetrating radar data, … All data acquisition at the star dune was concluded successfully, although the group was off to a late start. The…

  • Halftime reports from Erg Chebbi

    After three days of hard work in the field, Sunday was halftime workshop at HeidelErg. with diverse topics all around dunes, with and beyond the data collected in ErgChebbi. Manuel Herzog introduced the first results from the geophysical measurements with regards to dune stratification. Ground penetrating radar in combination with Electrical Resistivity Tomography already shows…

  • First results of our multi-method field course in an aeolian sand dune field

    During the first three days of the field course in Erg Chebi, data collection focussed on the star dune with groups of students applying different techniques of geophysical and topographic surveying. Today, data was checked to plan the remaining three field days. A recap of this intermediate data revision will follow. For today, we’d like…

  • Multi-method field course in an aeolian sand dune field

    This week, the research groups Geomorphology and 3DGeo of the Institute of Geography at Heidelberg University are conducting a field course in the aeolian sand dune field Erg Chebbi in Morocco. The current field course is the second edition of “HeidelErg“. The aim is to teach students different methods of data acquisition for physical geography,…
