  • Deriving sidewalk information using citizen science becomes #ProjectOfTheWeek

    We are happy to report that our task designed for the citizen science platform crowdcrafting.org was selected as their #ProjectOfTheWeek. This will help us to finish our experiment to derive information about sidewalks using Mapillary street level imagery with the support of the crowd very soon. Sidewalk information is an important resource for accessible route…

  • 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,…
