  • The importance of sidewalk information in OpenStreetMap for routing and navigation of people with restricted mobility

    Since the launch of OpenStreetMap (OSM) project in 2004, due to its nature and objective in collecting data from volunteers which are not necessarily familiar with GIScience and data collection procedures, the quality of gathered information has always been a main concern for both research and industrial communities. Several research studies have been conducted to…

  • Major Update for OpenRouteService Frontend

    Last few months, we have been working hard on a new Web frontend for OpenRouteService.org. The new service provides all features from the old OpenRouteService (Check the advanced version from the Options page) but is much faster and also covers all of Europe, Asia, Africa and Australia! Also further new route profiles will come within…

  • 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…

  • Visualising GPS data from OpenStreetMap using WebGL

    GPS data uploaded to the OpenStreetMap servers is a popular example of what is called Volunteered Geographic Information (VGI). The data has been (and is still) collected by the project contributors primarily to support mapping. As the inclusion of roads and paths in the map is a major goal of the project, the collected GPS…

  • Twitter location (sometimes) matters

    In contrast to photo-based VGI (e.g. Flickr) the correlation between the place where an information has been created and what the information is about is less intuitive for text-based VGI. In order to gain more insight into the relationship between text information generated in mobile contexts (e.g. via smartphones) and their recorded location, research has…
