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…

GIScience contributed to workshop “Open Data” in Heidelberg
Last friday the GIScience Research Group was invited to participate in a follow-up workshop on “Open Data”. Already in December 2015 the GIScience Research Group and the disastermappers heidelberg had been invited to present their work on Open Data in the 10th “Modellierungstag” of the Heidelberg Graduate School of Mathematical and Computational Methods for the…

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…
