  • Recent Progress in Automated Cartography at German Cartographers Day at INTERGEO

    The German Cartographers Day (Deutscher Kartographentag) is taking place at INTERGEO conference held in Stuttgart this week. We will present an update on recent progress in automated cartography in a talk by Andreas Reimer and Maxim Rylov about our latest improvements in automated label placement, which have been implemented in MapSurfer.NET as published as in OpenMapSurfer.uni-hd.de.…

  • Systematic review of current efforts to quantify the impacts of climate change on undernutrition

    Malnutrition is a challenge to the health and productivity of populations and is viewed as one of the five largest adverse health impacts of climate change. Nonetheless, systematic evidence quantifying these impacts is currently limited. Our aim was to assess the scientific evidence base for the impact of climate change on childhood undernutrition (particularly stunting)…

  • Quality Evaluation of OSM with Authoritative Data — a study of Land Use in Southern Germany

    Volunteered Geographic Information (VGI) such as data derived from the OpenStreetMap (OSM) project is a popular data source for freely available geographic data. There is frequently a cause of concern regarding the quality and usability of such data. In addition to our former studies (further here) or complementing our OSM in GIScience Book in a…

  • New research project: 4D Near Real-Time Environmental Monitoring (4DEMON)

    The Ministry of Science, Research and Arts, Baden-Wuerttemberg has funded a new research project called 4DEMON, which will approach the research front of 4D Near Real-Time Environmental Monitoring. Our physical environment underlies permanent changes in space and time with strongly varying triggers, frequencies, magnitudes and also consequences to humans. Monitoring of Earth surface processes (e.g.…

  • IJGIS Review for OpenStreetMap in GIScience Book

    The International Journal of Geographical Information Science (IJGIS) published a first review by Wen Lin at Taylor & Francis Online (DOI: 10.1080/13658816.2015.1077965) about our Springer book on OpenStreetMap in GIScience: experiences, research and applications, edited by Jamal Jokar Arsanjani, Alexander Zipf, Peter Mooney and Marco Helbich (2015, Springer Series: Lecture Notes in Geoinformation and Cartography,…

  • Matching GPS trajectories to street segments – an open source implementation

    We would like to inform about a new open source tool that allows matching of GPS trajectories to corresponding street segments. The tool implements a simplified version of the algorithm presented by Zhang et al. (2010). It is a JAVA based implementation and has been put under LGPL license. You can access the source code…

  • ISPRS Innsbruck PhD Summer School of Alpine Research 2015

    The first summer school of its kind on Close Range Sensing Techniques in Alpine Terrain took place in Obergurgl, Ötztal Valley, Austria, from July 5 – 11 2015. The event was co-hosted by the ISPRS, the main organizer University of Innsbruck and several other European universities including the GIScience Group of Heidelberg University. More than…

  • GIScience @AGIT/GI Forum conference 2015

    Last week members of the GIScience Research Group were attending the AGIT – Symposium and Exhibit for applied Geoinformatics in Salzburg. Beside the interesting welcome note given by Manfred Hauswirth from TU Berlin talking about the impact of Linked Data, the Internet of Things, and Clouds for Geospatial Information Systems, further keynotes and conference talks…

  • OpenRouteService at the Heidelberg wheelchair marathon

    On last Saturday we braved the tropical heat and used the occasion of the 13th international wheelchair marathon in Heidelberg to inform the public about our recent developments regarding wheelchair accessible route planning with OpenRouteService. We are thankful for the interesting conversations with people from Germany, Denmark, Japan, England and France and for their valuable…

  • Talk “Mixed-Scale Spatial Autocorrelation” in Osnabrück

    Last Tuesday, René Westerholt gave a talk about the assessment of spatial autocorrelation within social media data. It was part of the regular colloquium of the Institute for Geoinformatics and Remote Sensing at Osnabrück University. The talk provided an overview of challenges that occur due to the spatially and semantically mixed nature of social media…

  • Talk ‘3D Geodata – Background and Application’ given at Heidelberg University of Education.

    At Thursday, 2nd of July, Martin Hämmerle from the GIScience LiDAR Research Group gave a talk at the Geography colloquium series of the Heidelberg University of Education. Entitled ‘3D Geodata – Background and Application’, the talk introduced basics about 3D geodata and gave a broad overview to research projects of the chair of GIScience. The…

  • Extracting raw GPS data from OpenStreetMap – an LGPL tool

    We are happy to announce that a new JAVA-based tool is available that allows extracting raw GPS data from the OpenStreetMap GPS planet file. The tool is under LGPL license. It allows to specify a bounding box and to export the extracted data to 3D-Shapefiles. Besides the full GPS planet file there are also regional…
