A conceptual model for quality assessment of VGI for the purpose of flood management
Volunteered Geographic Information (VGI) has emerged as a potential source of geographic information for different domains. Despite the many advantages associated with it, such information lacks of quality assurance, since it is provided by individuals with different motivations and backgrounds. In response to this, several methods have been proposed to assess the quality of volunteered…

Guided Classification System for Conceptual Overlapping Classes in OpenStreetMap
The increased development of Volunteered Geographic Information (VGI) and its potential role in GIScience studies raises questions about the resulting data quality. Several studies address VGI quality from various perspectives like completeness, positional accuracy, consistency, etc. They mostly have consensus on the heterogeneity of data quality. The problem may be due to the lack of…

New publication: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.’
The results of a study dealing with photogrammetric 3D geodata of mass wasting sites conducted at the GIScience were considered to be worth publishing in the Journal of Applied Remote Sensing: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.‘ Three-dimensional (3D) geodata of mass…

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…
