  • Healthy Routing presented at the SemGeoSoc Workshop

    The current status of ou Healthy Routing research was presented in the SemGeoSoc Workshop hosted by the Zürich University and organized by prominent researchers in the area of geoinformatics. The workshop offered the opportunity for presenting and discussing ongoing work on the areas of location-based services supported by VGI, social media, citizen & science and…

  • 10 years of OSM data history with OSM API 0.5

    As our HeiGIT / GIScience team member Martin Raifer (tyr_asd) pointed out at his OSM diary, this weekend is the 10 year anniversary of OSM’s API version 0.5. He stresses the importance of this as “This is the version of the OSM-API that introduced (among other things) the version number on all OSM objects, making…

  • The OpenStreetMap folksonomy and its evolution

    The comprehension of folksonomies is of high importance when making sense of Volunteered Geographic Information (VGI), in particular in the case of OpenStreetMap (OSM). So far, only little research has been conducted to understand the role and the evolution of folksonomies in VGI and OSM, which is despite the fact that without a comprehension of…

  • 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…

  • Call for papers – PFGK18 : Photogrammetrie – Fernerkundung – Geoinformatik – Kartographie – 2018

    Feel free to submit papers to our DGPF Working Group on Geoinformatics (Prof. Haunert, Prof. Höfle). Important dates for submission can be found here: http://www.pf.bgu.tum.de/pfgk18/pfgk18_dat.html Deadline for regular papers is 31 October 2017!

  • Open land cover from OpenStreetMap and remote sensing

    In a recently published study (1), we produced a web based land use land cover (LULC) product based on OSM tags which are constantly updated by contributors/volunteers, and present a Remote Sensing based solution when tags were absent for a test site. We harness the combined benefit of an open source and ever-growing machine generated…

  • 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.…

  • DFG Summer School “VGI”

    Last week, our colleagues Franz-Benjamin Mocnik and René Westerholt participated in a summer school of the DFG priority programme on “VGI”. GIScience Heidelberg is involved in that programme by two projects, one of which is dealing with data quality issues and another one that investigates the assessment of spatial assotiations in social media data. The…

  • Workshop on Spatial Urban Analytics

    GIScience Heidelberg recently contributed to the Annual International Conference, which was held in the premises of the Royal Geographical Society and at the Imperial College in London. Together with João Porto de Albuquerque from the University of Warwick, our member René Westerholt convened two workshop sessions about “spatial urban analytics” on Friday 01 September (link…

  • LandSense Questionnaire

    http://bit.ly/2upEw7a <- LandSense Questionnaire LandSense aims to develop an online marketplace where companies that develop IT solutions using LULC data in one of three themes – urban, rural, and forestry, can acquire this information and further develop their products. By completing this questionnaire, you help us develop and further enhance our platform. Thank you very…

  • Study “Multiscale analysis and reduction measures of urban carbon dioxide budget based on building energy consumption” published

    The 3D spatial data processing group had the opportunity to collaborate with the team of Prof. Tzu-Ping Lin from National Cheng Kung University, Tainan, Taiwan, within the frame of a study dealing with carbon emission reduction measures in urban environments. One option of reducing carbon emission by buildings is to install photovoltaic (PV) panels in…
