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)…

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…
