On the last day of fieldwork in the rotmoos valley two groups (terrestrial laser scanning (TLS) and photogrammetry) set off to the rotmoos glacier again. A second TLS dataset was aqcuired
which enables the students to perform a change detection or deformation analysis.
The electrical resistivity tomography (ERT) group futher explored the pre-Quaternary [...]

Today was the second day of field work in the Rotmoos valley in the Ötztal Alps for our 16 students. The hot sun challenged the data acquisition but the impressive landscape makes up for every effort.
The terrestrial laser scanning group climbed up the valley flanks to acquire a high resolution point cloud from an end [...]

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 analysis of surface [...]

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 the [...]

The third workshop on 3D methods in geological applications was jointly organized by the University of Göttingen, the Geological Service of North Rhine-Westphalia (NRW, German federal state), and the 3D Geo Research Group at Heidelberg University. The workshop is an event of the initiative “3D Field Methods in Geosciences”, which provides a platform to connect [...]

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 and [...]

LiDAR meets Art

An interesting 3D art project using point clouds of the 3D Spatial Data Processing research group of Prof. Bernhard Höfle (3DGeo) was recently realized by artist Gerrit Frohne-Brinkmann. The data were acquired from natural karst cave features in the Dechen Cave near Iserlohn, Germany both with a low-cost Kinect sensor and terrestrial LiDAR.
For the art [...]
