On Tuesday, 16 November 2021, Dr Katharina Anders defended her PhD research with great success.
In her dissertation, Katharina developed methods on 4D change analysis to extract natural surface changes from near-continuous LiDAR time series of dynamic landscapes.
Congratulations, Katharina, for this excellent research - we are very proud to have you in our team and wish [...]

For the first time, the inland dunes in Sandhausen (Baden-Württemberg, Germany) have been captured by UAV-borne photogrammetry and laser scanning. The dunes are a precious habitat for many specialized plants and animals. They formed during the last ice age by sand drift from the Rhine valley. The large inland dunes, originally stretching from Karlsruhe to [...]

Within the AHK-4D project, we continually monitor topographic change at the alpine rock glacier Äußeres Hochebenkar in Austria. Based on multitemporal and multi-source 3D point clouds at up to two-week acquisition intervals, we are developing methods to quantify the magnitudes and frequencies of individual processes of topographic change over varying timescales.
This year, we have also [...]

On 25 June 2021, we celebrated together with the graduates of 2020/2021 of Bachelor and Master of Science in Geography, and also School Education (Lehramt) at the digital ceremony. Moreover, the rector of our University, Prof. Bernhard Eitel, gave an interesting talk about the history of the Institute of Geography. He outlined how a wide [...]

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 [...]

Curious, which methods on 3D/4D point cloud-based change analysis and virtual laser scanning we are working on, that might also be interesting for your research?
Thanks to a redesign of our 3DGeo website you can now quickly get an overview of algorithms and methods, that are acitvely developed in our research and featured in recent publications.
These [...]

The significance of gully filling practices on agricultural production has been only rarely evaluated in literature. In this study, a medium-sized catchment was selected, for being representative of the conventional farming practices on annual crops in the Campiña landscape in Southern Spain. During two wheat campaigns, an analysis of the spatial and temporal evolution of [...]
