  • European Handbook of Crowdsourced Geographic Information

    Recently, a new open access handbook edited by Capineri, et.al and supported by the European Commission – COST Action IC1203 (ENERGIC) has been published. This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and…

  • OpenFloodRiskMap Online combines Critical Infrastructure from OSM with Emergency Routing

    some time ago we deployed OpenFloodRiskMap (OFRM) at http://ofrm.geog.uni-heidelberg.de/ OpenFloodRiskMap (OFRM) is a prototype web application to assist decision makers in developing alarm and operation plans for flood risk management. The OFRM hereby provides support in accessing critical infrastructure (CI) information in the OpenStreetMap (OSM) data base and to furthermore add this information to an…

  • Two new DFG projects on VGI, OSM Quality and Social Media Analysis

    recently we were happy to receive the notification that two new research projects will be funded by the Deutsche Forschungsgemeinschaft (DFG) the German main funding agency for fundamental research. Both projects belong to the DFG Priority Programme “Volunteered Geographic Information: Interpretation, Visualisation and Social Computing“ (SPP 1894). The two projects are: A:) IntrisicOSMquality: A framework…

  • A Monitoring Tool for OpenStreetMap Mapathons in Python

    In the last couple of weeks disastermappers Heidelberg and GIScience members were interested in finding a way to monitor changes in the OpenStreetMap database. This could help to provide better feedback after mapathons and could allow to measure how many objects like buildings or roads were created or modified during a mapathon. (It was even…

  • A review of volunteered geographic information quality assessment methods

    While Volunteered Geographic Information (VGI) is gaining more and more popularity and VGI datasets are being used in various projects, there are always concerns about the quality of them. During the past years several studies have been performed regarding VGI quality assessment by employing different methods/approaches. However, if one needs to evaluate the quality of…

  • OpenRouteService 3.3 is going Mobile – Routing in the Americas, Gradients and more!

    In our latest release we have primarily focused on optimising and stabilising the backend and on adding new elements to provide an improved user experience throughout the OpenRouteService 3.3 based on OpenStreetMap data. After many requests from our community, we for starters can happily announce that we have made the service responsive for your mobile smartphones.…

  • A Two-Tiered Approach to OSM Data collection for Novice Users & Personalizing Walkability

    In addition to the two earlier presentations (No 1, No 2), today there are two additional presentations (No 3 & 4) by GIScience Heidelberg at AGILE 2016 conference in Helsinki: Rousell, A., Hahmann, S., Mobasheri, A. (2016): A Two-Tiered Approach to OSM Data collection for Novice Users. 19th AGILE Conference on Geographic Information Science. Helsinki,…

  • Deriving incline values for street networks from voluntarily collected GPS traces

    When producing optimal routes through an environment, considering the incline of surfaces can be of great benefit in a number of use cases. For instance, incline may be considered when computing the most energy-efficient routes for electric cars and bicycles. Likewise, pedestrians with restricted mobility (such as wheelchair users, parents with pushchairs, and the elderly)…

  • Revised set of tools published – CAP4Access e-Newsletter No. 4, May 2016

    CAP4Access e-Newsletter No. 4, May 2016 Revised set of tools published Dear Readers, The project has entered its third and final year at the start of 2016. After a successful project review in mid-February, the revised set of tools has now been made public. All CAP4Access tools deal with accessibility of the built environment and…

  • GIScience HD contributes to Int. Conference on Information Systems for Crisis Response and Management

    GIScience Heidelberg regularily contributes to the ISCRAM conferences. This year we again have four papers dealing with different aspects on crowdsoured geographic information (e.g. OpenStreetMap) in disaster response and management (e.g. OpenFloodRiskMap). Eckle, M., Herfort, B., Alberquerque, J., Leiner, R., Wolff, R., Jacobs, C., Zipf, A. (2016): Leveraging OpenStreetMap to support flood risk management: A…

  • Report on the 6th PCC meeting of CAP4Access EU project

    The 6th PCC meeting of CAP4Access EU project was held during 21st and 22nd of April in Vienna. Adam Rousell, Stefan Hahmann and Amin Mobasheri attended this meeting from GIScience research group of Heidelberg University.
