As part of the lecture “Geodatenerfassung”, geography students in their first semester turned theory of digital geodata acquisition into practice. Based on their aims and requirements, the students acquired geodata with different methods and sensors. Using a high-end Riegl VZ-2000i terrestrial laser scanner, two groups captured the old town of Heidelberg and a limestone [...]

On Thursday and Friday our group went further into the Erg in order to extend measurements from the last years on a large star dune arm and then spent one night in a dune camp.
Yesterday was the last day of field work in the Erg.The TLS group completed the data acquisition on a star dune and [...]

During the last three days of field work we not only acquired a lot of data at different sites in the Erg Chebbi. We also experienced various weather conditions including two sand storms, rain and sunny and hot days.
Yesterday, one group measured ground control points for satellite and photogrammetric point cloud data with an RTK [...]

After the participants of the practical field training had arrived in Fès yesterday and spent the evening there, the group is now on the way to the Erg Chebbi east of the Anti-Atlas mountains. Thereby, the group passes various gemorphologic landscape units including the Western Meseta, Middle Atlas and High Atlas mountains. Moreover, we crossed [...]

As part of the practical field training and the small research group “Erg Chebbi”, 16 students will explore physical geography and 3D GIScience in an impressive aeolian sand dune environment in Morocco from 5 October to 15 October. The Erg Chebbi is one of the smallest Ergs in the Sahara and is situated within the [...]

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 [...]

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 [...]
