A review of volunteered geographic information quality assessment methods (2017, background): “On the other hand OSM has also shown heterogeneity in coverage between diﬀerent places (Haklay 2010).”
Assuring the quality of volunteered geographic information (2012, methodology): “In another study of OpenStreetMap, Haklay et al. (2010) have shown that positional accuracy of a feature improves as the number of editors increases, but no further improvement is evident when the number of editors exceeds 13.”
A Comprehensive Framework for Intrinsic OpenStreetMap Quality Analysis (2014, background): “The completeness of the OSM road network plays a signiﬁcant role in routing and navigation applications and has therefore been the subject of several investigations (Girres and Touya 2010; Haklay et al. 2010; Kounady 2011; Ludwig et al. 2011; Neis et al. 2012).”
There's No Such Thing as the Perfect Map: Quantifying Bias in Spatial Crowd-sourcing Datasets (2015, background): “The former has been found to be very high [1, 10, 13, 14, 15, 16, 28] when compared to proprietary mapping datasets, in a variety of countries across Europe.”
Crowdsourcing for climate and atmospheric sciences: current status and future potential (2015, unknown): “…been noted in the literature (e.g. Raymond, 2001; Flanagin and Metzger, 2008; Snow et al. , 2008; Welinder et al. , 2010; Girres and Touya, 2010; Haklay et al. , 2010; Heipke, 2010; Goodchild and Glennon, 2010; Goodchild and Li, 2012; Basiouka and Potsiou, 2012; Neis et al. , 2012; Comber et…”
Analyzing the Contributor Activity of a Volunteered Geographic Information Project - The Case of OpenStreetMap (2012, methodology): “conducting similar studies to [32,40,43,44], in which the versions of an OSM object should be based on real changes and not primarily on the number of editors and the absolute version number.”
Geo-Wiki: An online platform for improving global land cover (2012, methodology): “More systematic attempts to assess the quality of crowdsourced information have been undertaken with regards to OpenStreetMap (OSM) data (Haklay, 2010; Haklay et al. 2010).”
The convergence of GIS and social media: challenges for GIScience (2011, background): “The massive amounts of VGI in general, and geotagged or location-based social-media data in particular, seem to revive our approach to the world from the perspective of place (Sui 2009), almost reaching the point of hyperlocalism dominated by ‘the tyranny of place’ (Haklay 2010).”
