  • New ‘Transformations to Sustainability’ project “Waterproofing Data” with UK and Brazil

    Recently a project proposal to the Belmont Forum and NORFACE joint programme Transformations to Sustainability (T2S) call has been accepted. The project “Waterproofing Data” investigates the governance of water-related risks, with a focus on social and cultural aspects of data practices. Typically, data flows up from local levels to scientific “centres of expertise”, and then flood-related…

  • A new infrastructure for exploring and analyzing OpenStreetMap

    Ever wondered how you can generate/use some meta-information about OpenStreetMap for your project? Are you interested in visualizing different aspects of OpenStreetMap data? In the article below, we present a server infrastructure to collect and process data about different aspects of OpenStreetMap. The resulting data are offered publicly in a common container format, which fosters…

  • Deadline extended to July 25: PLATIAL 2018, Heidelberg University

    Because of several requests the deadline for short papers has been extended to Wed. July 25 2018. The recent availability of user-generated geographic datasets allows gaining novel insights into otherwise hardly observable societal phenomena. Geosocial media forms one important source of user-generated information, which partly describes the everyday lives of people. The analysis of these…

  • Successful DFG VGIscience Collaborative Research Week in Heidelberg

    Last week about 30 scientists from different insitutions from all across Germany came together in Heidelberg to conduct collaborative research. The research week is the result of an intense collaboration within the DFG Priority Programme VGIscience, which deals with the following topics Information Retrieval and Analysis of VGI: • information extraction (space, time, semantics) •…

  • A discussion of crowdsourced geographic information initiatives and big Earth observation data architectures for land-use and land-cover monitoring

    The effective monitoring of land-use and land-cover changes (LULCC) is a basic requirement for understanding socio-enviromental processes of local to global scales. Remote sensing data and methods have long been established as the most effective approach for monitoring LULCC. The potential for further increasing the effectiveness of this approach is proportional to the astonishingly large…

  • Presentation on VGI and society: inequalities, exclusions and power asymmetries of user generated geoinformation

    This morning Georg Glasze and Thomas Bittner from Erlangen University gave a very interesting keynote talk on “VGI and society: inequalities, exclusions and power asymmetries of user generated geoinformation”. It was well received and lead to a lively discussion among the participants of the DFG SPP VGIscience Collaborative Research Week that is taking place this week…

  • Identifying the Effects of Mobility Domains on Volunteered Geographical Information: Towards an Analytical Approach

    The production of Volunteered Geographic Information (VGI) is a type of human behavior which emerges via direct and indirect interactions with the physical environments described by these data. The nature of these interactions and the extent to which they rely on physical presence in the mapped area may affect the quality of the resulting digital…
