  • ruprecht reports about CAP4Access activities

    “ruprecht”, the Heidelberg University’s student newspaper (~10.000 copies), reports about CAP4Access activities in its current issue (page 11, in German). We hope that some of the readers get interested in MapMyDay.org and OpenStreetMap.org and perhaps become new active contributors, which in the long run would also be beneficial for the wheelchair profile on OpenRouteService.org. Enjoy…

  • Support für Wheelmap – #MapMyDay

    Unser CAP4Access Projektpartner, der Berliner Verein Sozialhelden e.V., entwickelt seit mehreren Jahren die online frei verfügbare „Wheelmap.org“. Diese Karte basiert auf der OpenStreetMap und wird von Freiwilligen erstellt, die Informationen über die Barrierefreiheit von Orten, die sie schon selbst besucht haben, eintragen. Die Wheelmap enthält die Ziele, die barrierefrei erreicht werden können, unser OpenRouteService Wheelchair…

  • Matching OpenStreetMap Road Networks with Authority Data – a Polygon-based Approach

    Matching road network is an essential step for data quality assessment by using reference data. Conventionally, road network from two data sets are matched by using line-based approach which checks the similarity of properties of line segments. In new method recently published in IJGIS, a polygon-based approach is proposed to match OpenStreetMap road network with…

  • 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…

  • 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,…
