After three days of hard work in the field, Sunday was halftime workshop at HeidelErg. with diverse topics all around dunes, with and beyond the data collected in ErgChebbi.
Manuel Herzog introduced the first results from the geophysical measurements with regards to dune stratification. Ground penetrating radar in combination with Electrical Resistivity Tomography [...]

During the first three days of the field course in Erg Chebi, data collection focussed on the star dune with groups of students applying different techniques of geophysical and topographic surveying. Today, data was checked to plan the remaining three field days. A recap of this intermediate data revision will follow. For today, we’d like [...]

The Heidelberg LiDAR Operations Simulator (HELIOS) is an open source laser scanning simulation framework for interactive simulation and visualization of terrestrial, mobile and airborne laser scanning surveys. It can be flexibly used for teaching and training of laser scanning, development of new scanner hardware and scanning methods, or generation [...]

3DGeo licensed drone pilots

During the last weeks, members of the 3DGeo group were found studying for the “Kenntnisnachweisprüfung”, the official examination for drone pilots in Germany. Today, we are proud to announce that all six applicants from our group have passed both the theoretical test as well as a practical exam where they had to show their capability [...]

How can surface change processes be detected and delineated in large time series of 3D point clouds? A paper on the extraction of 4D objects-by-change has just been published in the ISPRS Journal of Photogrammetry and Remote Sensing. It presents an automatic method for 4D change analysis that includes the temporal domain by using [...]

How do the dynamics of surface change on a rock glacier look like over an entire summer season?
And how is rockfall activity and storage and talus supply from the headwall of a rock glacier related to patterns of its movement?

These and other questions are currently investigated within the AHK-4D and Geomorph4D projects of the 3DGeo [...]

From 22 - 25 June, the first field visit within the project AHK-4D - High-resolution and high-frequency monitoring of the rock glacier Äußeres Hochebenkar (AHK) in Austria took place in the Austrian Alps.
The aim of this project is to develop a methodology to quantify the magnitudes and frequencies of individual surface change processes of a [...]

A new paper on tree height estimation from TanDEM-X data has just been published in Remote Sensing of Environment. The article finds that tree height can be predicted using TanDEM-X metrics (backscatter, bistatic coherence, and interferometric height) in the sparse forest patches of the Arctic treeline zone at the transition from forest to tundra. Taking [...]
