Quality Evaluation of OSM with Authoritative Data — a study of Land Use in Southern Germany
Volunteered Geographic Information (VGI) such as data derived from the OpenStreetMap (OSM) project is a popular data source for freely available geographic data. There is frequently a cause of concern regarding the quality and usability of such data. In addition to our former studies (further here) or complementing our OSM in GIScience Book in a…

A Conceptual Quality Framework for Volunteered Geographic Information (VGI)
The assessment of the quality of volunteered geographic information (VGI) is cornerstone to understand the fitness for purpose of VGI in many application domains. Most analyses focus on the geometric and positional quality, and only sporadic attention has been devoted to the interpretation of the data, i.e., the communication process through which consumers try to…
