  • Annual Meeting 2015 of DGPF: German Society for Photogrammetry, Remote Sensing and Geoinformation

    The GIScience group Heidelberg participated actively in the 2015 Annual Meeting of the DGPF (German Society for Photogrammetry, Remote Sensing and Geoinformation), which took place 16-18 March 2015 in Cologne. Bernhard hold a keynote lecture on “LiDAR Point Cloud Information and Web Infrastructure for 3D Vegetation Analysis”, which was embedded in a special Workshop on…

  • Derivation of an OSM graph with TMC LCL traffic information to provide real time traffic services

    Increasing traffic, especially in urban areas, leads to more and more infrastructural bottlenecks and congestion inside transportation networks. The aim is therefore to use existing transport networks as efficiently as possible. Current traffic and incident reports from the Traffic Message Channel (TMC) are an important source of information to provide further services in the context…

  • Major Update for OpenRouteService Backend

    Last few months, we have been working hard on a new backend for OpenRouteService.org. The new implementation is much more flexible and faster than before and supports more sophisticated routing profiles. The services are deployed on a new and more powerful server that makes it possible to update routing graphs based on OpenStreetMap data more…

  • GIScience group participated in Open Data Day Mannheim

    Last Saturday (21/2) the GIScience group Heidelberg was part of the International Open Data Day. Open data enthusiasts all over the world teamed up to create new applications derived from open (not only governmental) data. The local open data day in Mannheim has seen 7 finished projects including Wikipedia edit wars analyses, public transport visualisations,…

  • Coverage of OSM highway features with corresponding GPS tracks

    As can be seen in the WebGL visualisation of the GPS data collected by the OSM contributors in Heidelberg (reported earlier in this blog), the quantity of recorded GPS tracks along an OSM highway features depends on the feature class. It has already been found before that the GPS data is not equally distributed among…

  • A Local Multi-Scale Spatial Autocorrelation Measure for Social Media Datasets

    Some time ago we reported about a new method for assessing spatial autocorrelation among points in social media datasets. A major contribution thereby is the ability of restricting the analysis to specific scales limited by both, an upper and a lower bound. The corresponding paper is now officially available online at IJGIS: Westerholt, R., Resch,…

  • Methods for Participation in Urban Planning in the Knowledge Society – New Project Accepted

    Recently a new joint project together with several groups at Heidelberg University has been accepted and is starting now. The interdisciplinary so called “Reallabor Urban Office” deals with sustainable urban development in the knowledge society and is coordinated by Prof. Gerhard (Geography of North America) and tightly linked to the Internationale Bauaustellung IBA Heidelberg. The…
