A review of volunteered geographic information quality assessment methods
While Volunteered Geographic Information (VGI) is gaining more and more popularity and VGI datasets are being used in various projects, there are always concerns about the quality of them. During the past years several studies have been performed regarding VGI quality assessment by employing different methods/approaches. However, if one needs to evaluate the quality of…

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)…

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…

OSM Mapathon for Ecuador Earthquake at Heidelberg University on Thursday April 21st
Last Saturday Ecuador was hit by a severe earthquake. Especially large parts of the coastal region have been devastated. Just a few hours later the Humanitarian OpenStreetMap team started first mapping actions to help producing the urgently needed geographic information and maps in OpenStreetMap. We want to participate in the relief work with a mapping…
