Publication of multi-sensor data from Arctic Siberian permafrost site
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…

Auto3Dscapes for 4D Beach Observation
How does a sandy beach naturally restore after a storm event? Invaluable information on this process is provided by a highly temporal (hourly) time series of 3D point cloud data acquired over several months at the beach of Kijkduin (NL). The permanent LiDAR system is operated by a team of TU Delft researchers in the…

Simulate LiDAR Acquisitions with HELIOS
Did you ever consider planning and testing your LiDAR campaign in a computer simulation? Would you like a flexible means to generate 3D point cloud data for developing or testing methods? This is easily possible with the laser scanning simulation framework HELIOS (Heidelberg LiDAR Operations Simulator). There have been major new developments since the first…

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 (#4): Exploring high-mountain 3D GIScience
We are blogging live from Ramolhaus at 3006 m a.s.l. After a 4-hours hiking tour with 1100 height meters we are now enjoying the impressive view over glaciers with “Kaiserschmarren” for lunch.

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…
