3D Geospatial Data Processing (3DGeo) Research Group
We investigate the extraction of geoinformation from 3D/4D geodata (predominantly point clouds), which were acquired with cutting-edge Earth observation technology (e.g. 3D laser scanning, photogrammetry and SAR). Emphasis is put on the exploitation of multitemporal geographic 3D data, which enables near real-time 3D/4D mapping and observation. A major focus lies on the development of computational methods for 3D/4D geospatial data processing and analysis by making use of the full sensor data streams (e.g. LiDAR backscatter). It is aimed at increasing the understanding of geographical phenomena. Our methods and tools are applied to multi- and interdisciplinary research questions in the broad field of Digital and Computational Environmental Sciences. This covers landscapes dominated by physical processes (e.g. geomorphology), man-made landscapes (e.g. renewable energies) and strong human-environmental interactions (e.g. agriculture, natural hazards, health and geoarchaeology). Our research sites are spread all over the world: we perform in-situ measurements, program in the lab and simulate Earth observation in virtual environments.

We would like to invite you to contribute actively to the DGPF Annual Conference 2020 (Jahrestagung) in Stuttgart. Deadline for abstract submissions (500-1500 words) is 31 October 2019. Our Working Group for Geoinformatics is looking forward to recent research and workbench insights covering the full range of methods in geoinformatics. Go for it and submit your [...]
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 [...]
Change analysis of rock glaciers is crucial to analyzing the adaptation of surface and subsurface processes to changing environmental conditions at different timescales because rock glaciers are considered as potentially unstable slopes and solid water reservoirs. To quantify surface change in complex surface topographies with varying surface orientation and roughness, [...]
3DGeo group member Lukas Winiwarter was awarded the third place of this year’s AGEO award at the AGIT2019 in Salzburg for his diploma thesis on “Classification of 3D Point Clouds using Deep Neural Networks”. It was carried out at TU Wien under the supervision of Dr. Gottfried Mandlburger and Prof. Dr. Norbert Pfeifer, and has [...]
We cordially invite everybody interested to our next open GIScience colloquium talk! The speaker is Dr. Anette Eltner TU Dresden, Institute of Photogrammetry und Remote Sensing When: Monday 01.07.2019, 2:15 pm Where: INF 348, room 015 (Institute of Geography, Heidelberg University) Image processing for geomorphological and hydrological monitoring The potential of images to answer research questions in geosciences is vast. Earth observation [...]
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 [...]
Close-range sensing techniques in Alpine terrain have been taught in the frame of a bi-annual ISPRS summer school since 2015. This week, a group of 40 young researchers (mainly PhD students) is participating in the third edition of the summer school to learn about various sensors, processing techniques, and analysis methods for different topics in [...]
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 [...]
This week, the 3DGeo participated in the ISPRS Geospatial Week 2019 with two presentations among the sessions of the Laser Scanning Workshop with many interesting talks and poster. Presentations were given by Ashutosh Kumar in the Machine Learning Session and Katharina Anders in the Change Detection Session. Highlight: The work by Ashutosh Kumar on feature relevance in [...]
Namibia is a dry and low populated country highly dependent on agriculture, with many areas experiencing land degradation accelerated by climate change. One of the most obvious and damaging manifestations of these degradation processes are gullies, which lead to great economic losses while accelerating desertification. The development of standardized methods to [...]
