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 [...]

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 [...]

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 [...]
