Live from the Ötztal Alps (#1): Exploring high mountain 3D geoinformation
As part of the practical field training “3D Geodatenerfassung im Hochgebirge (Ötztal)”, 29 July – 04 August, 16 students explore pyhsical geography in an impressive high-mountain environment in the Ötztal valley, Austria. With the help of terrestrial LiDAR, RTK GNSS, close range photogrammetry and electrical resistivity tomography (ERT), multi-source datasets will be captured for the…

Continued capturing of an active rock glacier in 3D
For the fourth consecutive year, the 3DGeo team acquired the rock glacier Äußeres Hochebenkar in the Austrian Ötztal by terrestrial laser scanning. This adds another point cloud to the multitemporal dataset to observe how the active rock glacier changes over the years. In an elevation over 2600 m a.s.l., the complex terrain on and around…

Validation of fracture data recognition in rock masses by automated plane detection in 3D point clouds
Digital outcrop models provide a powerful data basis to obtain orientation information on rock masses. Robust and transferrable automatic methods are required to process and analyze these data, as outcrops and hence acquired 3D point clouds are influenced by varying conditions depending e.g., on the site, atmospheric conditions and other factors. A crucial aspect in…

Auto3Dscapes Makes Environmental Monitoring Smarter
… by acquiring data only when and where changes occur. In this project on Autonomous 3D Earth Observation of Dynamic Landscapes (Auto3Dscapes), a novel strategy of permanent 3D observation will be developed incorporating observed topographic changes as feedback and dynamically adapting the acquisition parameters and analysis methods. Permanent 3D Earth observation is currently challenged by…

3D geodata acquisition in the Siberian Arctic
In September 2017, the 3D Spatial Data Processing Group (3DGeo) joined the German-Russian expedition of the Alfred Wegener Institute (AWI) for Polar and Marine Research to the Arctic research station Samoylov (N 72°22’, E 126°29’) in the central Lena Delta. Under the lead of Julia Boike, the research team maintained and expanded long-term monitoring stations…
