HeidelErg – live from the Erg Chebbi in Morocco (#2): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
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…

HeidelErg – live from the Erg Chebbi in Morocco (#1): Exploring physical geography and 3D GIScience in an aeolian sand dune field.
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…

Capturing Flood Risk Perception via Sketch Maps
The flood risk perception of people living in areas at risk can be a valuable source of information for mitigation and preparedness within disaster management. We apply a method based on sketch maps and questionnaires to capture this flood risk perception during case studies in Santiago de Chile. Results of our study can be found…

Continuing ground-based measurements at Arctic research site
For the fourth consecutive year, ground-based measurements of the dynamic, permafrost-underlain tundra landscape have been continued in Trail Valley (68°44’25” N 133°29’36” W). A team of permafrost researchers from the Alfred Wegener Institute (AWI) for Polar and Marine Research around PD Dr. Julia Boike conducted the measurements as part of a large expedition to the Canadian Northwest…

Live from the Ötztal Alps (#5): Exploring high-mountain 3D GIScience
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…

Live from the Ötztal Alps (#3): Exploring high mountain 3D geoinformation
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 relief in…

Live from the Ötztal Alps (#2): Exploring high mountain 3D geoinformation
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…

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…

3D WebGIS: From Visualization to Analysis. An Efficient Browser-Based 3D Line-of-Sight Analysis
3D WebGIS systems have been mentioned in the literature almost since the beginning of the graphical web era in the late 1990s. The potential use of 3D WebGIS is linked to a wide range of scientific and application domains, such as planning, controlling, tracking or simulation in crisis management, military mission planning, urban information systems,…
