Data publication: Point clouds of snow-on and snow-off forest site
A new dataset of UAV and terrestrial laser scanning point clouds of snow-on and snow-off conditions at a Black Forest site (Hundseck, 48.643°N, 8.228°E) was published open access: Winiwarter, L., Anders, K., Battuvshin, G., Menzel, L. & Höfle, B. (2023): UAV laser scanning and terrestrial laser scanning point clouds of snow-on and snow-off conditions of…

New paper on “improving change analysis with full temporal information”
In recently published work, we show how change analysis from near-continuous 3D time series improves by considering full temporal information. How can it be done? Using 4D objects-by-change! The method was applied to an hourly time series of terrestrial laser scans acquired for snow cover monitoring. In the snow-covered scene at the Zugspitze ski resort,…

Measuring the tallest sequoias of Germany in student field campaign
Last Fieldwork Friday, a group of students gathered in Arboretum I to capture Heidelberg’s sequoia trees in the frame of a 3D Sensor Practical. In small groups, the students learned surveying strategies via terrestrial laser scanning (TLS) and Global Navigation Satellite System (GNSS) measurements. It was one of the first joint field campaigns of our…

3D Winter Wonderland – Multi-method acquisition for snow process research
A joint field campaign was conducted this week in the snow-covered black forest (Hundseck, 48.643°N, 8.228°E) by the research groups Hydrology and Climatology (Prof. Menzel) and 3DGeo (Prof. Höfle). Regular in-situ surveys are conducted at the site to investigate snow as crucial component of the hydrologic cycle, forest management, and evapotranspiration. Surveys comprise measurement of…

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…

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…
