Freiwilligentag 2018 – Aufruf zur Teilnahme an der „Routenplaner-Erfassungsrallye“ der Stadt Heidelberg am 15.09.
Wie komme ich als Rollstuhlfahrerin oder Rollstuhlfahrer am besten vom Bismarckplatz zum Rathaus? Welche Wege ohne Hindernisse können Eltern mit Kinderwagen nutzen? Helfen soll dabei ein neuer Routenplaner der Stadt Heidelberg. Der Routenplaner basiert auf dem OpenRouteService der Abteilung Geoinformatik der Universität Heidelberg und wurde in einem gemeinsamen vom Ministerium für Inneres, Digitalisierung und Migration Baden-Württemberg geförderten Projekt um […]
Enrichment of OpenStreetMap Data Completeness with Sidewalk Geometries for Wheelchair Routing
Tailored routing and navigation services utilized by wheelchair users (such as provided by OpenRouteService.org ) require certain information about sidewalk geometries and their attributes to execute efficiently. Except some minor regions/cities, such detailed information is often not sufficiently present in current versions of crowdsourced mapping databases including OpenStreetMap. In a recent study (1) we aim […]
Today OpenRouteService at 7th GeoIT WhereCamp Conference Berlin
Today we present the latest version and details on the technical API of OpenRouteService at the 7th GeoIT WhereCamp Conference Berlin. Tim from the Heidelberg Institute for Geoinformation Technology (HeiGIT) will talk about Consuming Open Data for Highly Customizable Route Planning He will show some examples of the very rich feature set and API of OpenRouteService […]
Interview on Crowdsourcing for Optimized Cycle Routes
On the occasion of the international Bike2Work Day the radio Berlin Brandenburg (RBB) conducted a short interview with Prof. Alexander Zipf (GIScience HD/ HeiGIT). It was about current research and development work at the GIScience Research Group Heidelberg and HeiGIT, which involve the use of user-generated geodata for investigations between cycling behaviour and health, as well as […]
CAP4Access Comes to a Close
On Tuesday 17th January, the CAP4Access/MyAccessible.EU came to a close after three years with the successful completion of the final European Commission review meeting in Brussels. Reviewers were highly pleased with the outcomes of the project, both on the technical and societal fronts. At GIScience in Heidelberg, through the EC FP7 project we have extended […]
Why is it routing this way?
When using routing services that rely on OpenStreetMap data, the route engine might suggest you a path that seems to be longer than the shortest possible route you could identify on the map. The main reason behind this are either a lack of data completeness in OSM (for certain data attributes/ for certain regions) or […]
