Towards quality metrics for OpenStreetMap [PDF]

Proceedings of the 18th SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2010
Volunteered Geographic Information (VGI) is currently a "hot topic" in the GIS community. The OpenStreetMap (OSM) project is one of the most popular and well supported examples of VGL Traditional measures of spatial data quality are often not applicable to OSM as in many cases it is not possible to access ground-truth spatial data for all regions ...
