Information Extraction from LiDAR Intensity Data and Multispectral LiDAR Technology
LiDAR is a consolidated technology for topographic mapping and 3D reconstruction, which is implemented in several platforms On the other hand, the exploitation of the geometric information has been coupled by the use of laser intensity, which may provide additional data for multiple purposes. This option has been emphasized by the availability of sensors working…

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,…

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.…
