3D micro-mapping: Towards assessing the quality of crowdsourcing to support 3D point cloud analysis
Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded…

Trace element partitioning in fluvial tufa reveals variable portions of biologically influenced calcite precipitation
Freshwater tufas are widespread phenomena in karst environments denoting important terrestrial paleo-environmental and paleoclimate archives. Additionally, many tufa sites are UNESCO world natural heritages, which emphasizes their societal importance (e.g. Jiuzhaigou, China; Plitvice, Croatia) and the demand for comprehensive conservation and monitoring strategies. Formation of tufas is controlled by numerous factors. The latest publication –…

Digital Geoarchaeology: New Techniques for Interdisciplinary Human-Environmental Research
Digital Geoarchaeology can be regarded as an intersection of disciplines that contributes to the consolidation of different academic perspectives. It represents a novel approach in terms of computer scientific methods combined with geoscientific know-how and archaeological expertise to multi-methodically investigate past human-environmental relationships (Siart et al. 2018). In the new textbook “Digital Geoarchaeology” by Springer,…

Cover Story of ISPRS International Journal of Geo-Information
Not undercover but on the cover: We were selected as cover story of the ISPRS International Journal of Geo-Information, Volume 6, Issue 11. In our research on “Historic Low Wall Detection via Topographic Parameter Images Derived from Fine-Resolution DEM“, we apply rapid landscape line detection to extract historic vegetable garden walls based on topographic information…

Mobile low-cost 3D camera maize crop height measurements under field conditions
Maps of the spatial distribution of crop heights can strongly support agriculture in terms of efficiency and yield optimization. Recently published results of experiments of the 3D Spatial Data Processing research group describe an approach to easily extend regular agricultural machines with low-cost sensors for capturing crop heights while the machine is in the field.…

LiDAR meets Art
An interesting 3D art project using point clouds of the 3D Spatial Data Processing research group of Prof. Bernhard Höfle (3DGeo) was recently realized by artist Gerrit Frohne-Brinkmann. The data were acquired from natural karst cave features in the Dechen Cave near Iserlohn, Germany both with a low-cost Kinect sensor and terrestrial LiDAR. For the…
