  • New HORIZON 2020 project “WeGovNow” – Towards We-Government: Collective and participative approaches for addressing local policy challenges

    Recently a new 3 year EU project in the HORIZON 2020 programme has been accepted and is about to start now. WeGovNow is aiming at using state-of-the-art digital technologies in community engagement platforms to engage citizens in decision making processes within their local neighbourhood. It aims at bringing together multiple citizen-driven systems into a single…

  • Temporal Analysis on Contribution Inequality in OpenStreetMap: A Comparative Study for Four Countries

    Contribution inequality widely exists in OpenStreetMap (OSM), which means that most data come from a minority of the contributors, while the majority only accounts for a small percentage of data. This phenomenon is of great importance to understanding from where the data come and how the project evolves. The investigation in a recently published paper…

  • MyAccessible.EU OpenStreetMap Tools for People with Reduced Mobility Released

    As part of the MyAccessible.EU project (CAP4Access) several tools have been developed at GIScience in Heidelberg. These tools aim at collecting information about accessibility of places and to assist in movement through environments for people with reduced mobility. These tools include a mobile (Android) and web application for the collection and display of obstacles in…

  • 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…

  • Castle accessibility mapping is part of a short documentary

    Our efforts related to the mapping of the accessibility of places and ways at Heidelberg castle are now part of a short documentary produced by Beirat von Menschen mit Behinderung Heidelberg (Advisory Board of people with disabilities Heidelberg), with whom we cooperate in the scope of the CAP4ACCESS project. As a follow-up of this event,…

  • 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…

  • New Collaboration on Crowdsouring for Forensic Disaster Analysis with KIT

    The aftermath of disasters – such as the recent Nepal earthquake – have shown that the general public can contribute to the response of a disaster event and moreover is able to organize and engage itself across national borders. Digital volunteerism is offering unique capabilities to bridge information gaps, particularly in crisis situations where infrastructure…

  • New DFG Project on Data Integration from Location Based Social Networks

    Recently a new project has been accepted to be funded by the Deutsche Forschungsgemeinschaft (DFG). It deals with an agent-based and quality-aware integration of geo-social network data, thus investigating data integration as a collaborative negotiation process. Web-based social networks are now a significant social phenomenon. The user-generated data produced through them, including the location-based data,…

  • A Conceptual Quality Framework for Volunteered Geographic Information @ COSIT 2015 this Tuesday
