  • Today & tomorrow GIScience Heidelberg Talks in Africa and Australia

    This Wednesday and Thursday we have presentations from the GIScience research group Heidelberg on two remote contintents – both in Africa and in Australia: On Wednesday: First down under at GIScience Melbourne in Australia Rene Westerholt will present the work related to our PLATIAL18 workshop: Westerholt, R., Gröbe, M., Zipf, A. and Burghardt, D. (2018): Towards the statistical…

  • GIScience Heidelberg @ GIScience Melbourne

    Two papers from GIScience Heidelberg have been contributed to and accepted for the 10th International GIScience Conference 2018 in Melbourne, Australia. They will be presented on Wednesday and Thursday respectively. Looking forward to a fruitful discussion! Westerholt, R., Gröbe, M., Zipf, A. and Burghardt, D. (2018): Towards the statistical analysis and visualization of places. 10th…

  • Towards the statistical analysis and visualization of places

    The concept of place recently gains momentum in GIScience. In some fields like human geography, spatial cognition or information theory, this topic already has a longer scholarly tradition. This is however not yet completely the case with statistical spatial analysis and cartography. Despite that, taking full advantage of the plethora of user-generated information that we…

  • Follow-up to study with mobile low-cost 3D camera crop height measurements

    The study “Mobile low-cost 3D camera maize crop height measurements under field conditions” (see the respective blog entry) is now available also as print version: The updated citation is: Hämmerle, M. & Höfle, B. (2018): Mobile low-cost 3D camera maize crop height measurements under field conditions. Precision Agriculture 19(4), pp. 630-647. doi: 10.1007/s11119-017-9544-3.

  • GIR’17 Workshop on Geographic Information Retrieval at HD University

    This week the 11th Workshop on Geographic Information Retrieval (GIR’17) will be held at Mathematikon, Heidelberg University, Germany. This workshop will address all aspects of Geographic Information Retrieval – such as the provision of methods to identify geographic scope, retrieve and relevance rank documents or other resources from both unstructured and partially structured collections on…

  • GIScience at Fachaustausch Geoinformation 2017

    On November 23d, the 9th “Fachaustausch Geoinformation“, a yearly networking  event  for professionals in the geodata and geoinformation domain organised by GeoNet.MRN, took place in Heidelberg’s Print Media Academy. GIScience research group at Heidelberg University and HeiGIT (Heidelberg Center for Geographic Information Technology) presented current research and projects at the event’s exhibition. Theresia Bauer, Baden-Württemberg’s Minister…

  • 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.…

  • 3D geodata acquisition in the Siberian Arctic

    In September 2017, the 3D Spatial Data Processing Group (3DGeo) joined the German-Russian expedition of the Alfred Wegener Institute (AWI) for Polar and Marine Research to the Arctic research station Samoylov (N 72°22’, E 126°29’) in the central Lena Delta. Under the lead of Julia Boike, the research team maintained and expanded long-term monitoring stations…

  • 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…

  • GIScience group members at the ISPRS Geospatial Week 2017 in Wuhan, China

    Last week (Sept. 18-22, 2017), our six colleagues, Prof. Alexander Zipf, Doctoral Candidate Xuke Hu, Dr. Hongchao Fan, Dr. Martin Hämmerle, Dr. Zhiyong Wang, and Dr. Wei Huang, participated in the ISPRS Geospatial Week 2017 held in Wuhan, China. In the opening ceremony on Sept. 18, 2017, the U.V. Helava Award was presented to Dr.…

  • 3D bathymetry measurements in shallow-water environments with a low-cost sensor – study published

    To take bathymetric measurements in areas with shallow water is very challenging for methods such as SONAR or bathymetric LiDAR. In our study “Assessing the Potential of a Low-Cost 3-D Sensor in Shallow-Water Bathymetry”, we examine the performance of a low-cost 3D camera when capturing bathymetry in waters up to 0.4 m depth. The tested…
