  • AGIT30 was ohsome (and awesome)

    Members of the HeiGIT team were presenting parts of our work at this years AGIT/GI_Forum conference in Salzburg, Austria (as already announced in a previous blogpost). Julian Bruns was presenting the results of a joint work with the KIT and his old employer, the FZI, which is published in the GI-Forum journal (English conference running in parallel to the…

  • 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.

  • Continued capturing of an active rock glacier in 3D

    For the fourth consecutive year, the 3DGeo team acquired the rock glacier Äußeres Hochebenkar in the Austrian Ötztal by terrestrial laser scanning. This adds another point cloud to the multitemporal dataset to observe how the active rock glacier changes over the years. In an elevation over 2600 m a.s.l., the complex terrain on and around…

  • A new infrastructure for exploring and analyzing OpenStreetMap

    Ever wondered how you can generate/use some meta-information about OpenStreetMap for your project? Are you interested in visualizing different aspects of OpenStreetMap data? In the article below, we present a server infrastructure to collect and process data about different aspects of OpenStreetMap. The resulting data are offered publicly in a common container format, which fosters…

  • Deadline extended to July 25: PLATIAL 2018, Heidelberg University

    Because of several requests the deadline for short papers has been extended to Wed. July 25 2018. The recent availability of user-generated geographic datasets allows gaining novel insights into otherwise hardly observable societal phenomena. Geosocial media forms one important source of user-generated information, which partly describes the everyday lives of people. The analysis of these…

  • Colloquium on Big spatio-temporal data analysis based on social sensing

    We cordially invite everybody interested to our next open GIScience colloquium talk The speaker is Prof. Jiangya Gong Dean, School of Remote Sensing and Information Engineering, Wuhan University, China When: Monday 09.07.2018, 2:15 pm Where: INF 348, room 015 (Institute of Geography, Heidelberg University) Big spatio-temporal data analysis based on social sensing With the rapid development of…

  • Validation of fracture data recognition in rock masses by automated plane detection in 3D point clouds

    Digital outcrop models provide a powerful data basis to obtain orientation information on rock masses. Robust and transferrable automatic methods are required to process and analyze these data, as outcrops and hence acquired 3D point clouds are influenced by varying conditions depending e.g., on the site, atmospheric conditions and other factors. A crucial aspect in…

  • 1 Million ways to download OpenStreetMap data workshop

    OpenStreetMap has become a huge source for any kind of geographic information. In OpenStreetMap you now find not only street information, but also information related to buildings, shops, sights and in Heidelberg even to individual trees. Furthermore, OpenStreetMap data is open data – everyone is free to edit and to download the data to create own…

  • Talk on methods and applications for large geospatial point clouds

    On Wednesday, Roderik Lindenbergh from TU Delft (NL) gave an exciting talk on robust geometry extraction in large spatial point clouds in the frame of the IWR colloquium at the Interdisciplinary Center for Scientific Computing. With focus on robust and novel methods of geoinformation extraction from these special datasets, the audience was taken on a…

  • Introducing the Critical Numbers Tool for the HOT Tasking Manager

    We would like to introduce our new little analysis tool Critical Numbers for projects of the HOT Tasking Manager. (You can find this blogpost and the code for the tool at our GitHub repository.) The Critical Numbers webapp is an easy way to visualize how much of a project is mapped and validated – results…
