Navigation Intelligence & Location Based Services

Analyses and Utilization of Volunteered Geographic Information (VGI) from the Crowd for Mobility, Navigation and Routing Services

Navigation and Routing play an important role for different kinds of purposes within the context of mobility. For example logistics companies depend on optimized access routes for freight deliveries, while hikers and cyclists continually seek for individually adapted trails. Answering such individual requirements needs a sophisticated set of specialized routing and navigation profiles, optimized for the specific user. To this end, we process and enhance rich and crowd-generated Volunteered Geographic Information to deliver specific services providing maximum benefit for the user.

Our Services

  • Traffic- and Mobility Solutions, Accessibility Analysis, Data Analysis and Modelling related to Mobility and Transportation
  • Development of Cloud-Services and APIs for specific Routing- and Navigation solutions with global coverage
  • Design and Development of both Web- and Mobile Applications using the Spatial Context
  • Many years of expertise in OpenStreetMap-based Services and Quality Assurance of user-generated content

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 [...]

Barrierefreier Routenplaner: neue Daten für Rollstuhlrouting in Heidelberg

Wie komme ich als Rollstuhlfahrer am besten vom Marktplatz zur Stadthalle? Und welche Wege ohne Hindernisse bieten sich für Eltern mit Kinderwagen durch die Altstadt an? Ein neuer Routenplaner auf Basis von openrouteservice.org soll künftig barrierefreie Wege in Heidelberg aufzeigen, zunächst in der Altstadt und in Bergheim. Seit Dezember 2017 arbeitet die Stadt Heidelberg in Kooperation [...]

Openrouteservice-py now available on PyPi - Easy Routing, Geocoding, Isochrones and Matrix Routing with Python!

We have finally developed a pretty handy python API for all of you pythoniasts out there. This library makes requests to the openrouteservice API extremely simple. With this you will be able to query the following services with a couple of lines of python code. directions matrix geocoding isochrones To provide a quick and dirty example:: import openrouteservice coords = ((8.34234,48.23424),(8.34423,48.26424)) client = [...]

New Real-time OSM service provides custom up-to-date Extracts of OpenStreetMap Data

Disaster events damage human infrastructure and its surroundings within seconds. To support humanitarian logistics, the Disaster OpenRouteService needs the latest, most accurate data available. While crowd-sourcing OSM updates during disasters proved very successful, there is not yet a convenient way of automatically accessing up-to-date OSM data for specific regions of interest. Addressing this need, HeiGIT [...]

Routing through open spaces – a performance comparison of algorithms

Finding the shortest path through open spaces is a well-known challenge for pedestrian routing engines. A common solution is routing on the open space boundary, which causes in most cases an unnecessarily long route. A possible alternative is to create a subgraph within the open space. In a recently published paper authors from GIScience Research [...]
