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 data [...]

A 16-year record (2002–2017) of permafrost, active-layer, and meteorological conditions at the Samoylov Island Arctic permafrost research site, Lena River delta, northern Siberia was just published in Earth System Science Data. The long-term observational data is complemented by high-resolution topographic data acquired by terrestrial laser scanning (TLS) in 2017, when the 3DGeo Research Group joined [...]

On our last day in the Ötztal Alps, we had an exciting excursion from Obergurgl to Ramolhaus on 3006 m a.s.l. On our way up we could directly explore glacial history by passing the historical extents and related moraines of the retreating Gurgler glacier. The students also learned about geoarcheology and settlement history in the [...]

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 [...]

Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded [...]

Participatory Sensing (PS) is a concept which enables laymen to easily gather geodata with standard low-cost mobile devices, offering new and efficient opportunities for agricultural monitoring. The integration of local agricultural knowledge may help to better understand complex phenomena such as the association between climate variability, crop yields and undernutrition.
In our new study we present [...]

This summer semester’s laser scanning course comprises a series of field trips done by small student groups of maximum two persons. Campaign planning and hands-on laser scanning in the field were conducted by the students and supervised by professor Bernhard Höfle, tutor Jörn profe, Kristina König, and Martin Hämmerle. Intensive learning for each single [...]
