  • 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…

  • Mapping of environmental risk factors in everyday life

    Psychiatric research is increasingly interested in the influence of social and environmental contexts on human health. According to recent findings, specific impacts of urban upbringing on neural social stress processing relate to the heightened prevalence of mental disorders in cities. Although this is a major societal problem, it remains unknown which environmental components (e.g., psychosocial…

  • 3D Participatory Sensing for Crop Height Assessment

    Participatory Sensing (PS) is a concept which enables laymen to easily gather geodata with standard low-cost mobile devices, offering new and efficient opportunities for agricultural monitoring. The integration of local agricultural knowledge may help to better understand complex phenomena such as the association between climate variability, crop yields and undernutrition. In our new study we…

  • Amateur or Professional: Assessing the Expertise of Major Contributors in OpenStreetMap Based on Contributing Behaviors

    Volunteered geographic information (VGI) projects, such as OpenStreetMap (OSM), provide an alternative way to produce geographic data. Research has showed that the resulting data in some areas are of decent quality, which guarantees their usability in various applications. Though these achievements are normally attributed to the huge heterogeneous community mainly consisting of amateurs, it is…

  • A Conceptual VGI Quality Framework – chapter published in ‘Spatial Information Theory’

    Now the book “Spatial Information Theory” has been published in electronic and print format. It includes full papers from the COSIT – CONFERENCE ON SPATIAL INFORMATION THEORY XII 2015, including our paper: Ballatore, A. and Zipf, A. (2015): A Conceptual Quality Framework for Volunteered Geographic Information. In: Fabrikant, S.I., Raubal, M., Bertolotto, M., Davies, C.,…

  • Yet another little Paper Meta-Statistics

    uuuhh, we just realized that we have the most cited papers in both the “ISPRS International Journal of Geographic Information” (IJGI) as well as in the journal “Future Internet” (according to the journals counting). Additionally also in both most cited lists of the two journals we each have a paper on place four. Further two…

  • Call for Paper: Special Issue on Volunteered Geographic Information (VGI) in ISPRS International Journal of Geo-Information

    Parallel to the advent of Web 2.0 technologies, volunteered geographic information (VGI) has emerged as a novel form of user-generated content, which involves both active forms of contribution such as online mapping or the explicit georeferencing of various media as well as the passive collection of data via the user’s location-enabled smartphone. Due to an…

  • 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…

  • 3D-WebGIS for Archeology – the example of MayaArch3D

    Archaeological projects increasingly collect airborne LiDAR data to use as a remote sensing tool for survey and analysis. Publication possibilities for LiDAR datasets, however, are limited due to the large size and often proprietary nature of the data. Fortunately, web-based, geographic information systems (WebGIS) that can securely manage temporal and spatial data hold great promise…

  • 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…

  • Contributions to the European Handbook on Crowdsourced Geographic Information

    The GIScience Research Group at Heidelberg University has contributed several chapters to the forthcoming “European Handbook of Crowdsourced Geographic Information”, edited by Capineri, C. et al. (eds.), Ubiquity Press. This includes the following chapters and papers that have been accepted for publication from different authors of the GIScience Research Group Heidelberg: – Research on social…
