Assessment of volunteered geographic information for vegetation mapping
Environmental Monitoring and Assessment, 2020Vegetation mapping requires extensive field data for training and validation. Volunteered geographic information in the form of geotagged photos of identified plants has the potential to serve as a supplemental data source for vegetation mapping projects.

The credibility of volunteered geographic information
GeoJournal, 2008The proliferation of information sources as a result of networked computers and other interconnected devices has prompted significant changes in the amount, availability, and nature of geographic information. Among the more significant changes is the increasing amount of readily available volunteered geographic information.

Volunteered geographic information (VGI) can provide field samples for predictively mapping geographic phenomena. Yet the biased spatial coverage of VGI observations often undermines the fitness of use of VGI samples for predictive mapping.

Assuring the quality of volunteered geographic information
Spatial Statistics, 2012Abstract Volunteered geographic information (VGI) is a phenomenon of recent years, offering an alternative mechanism for the acquisition and compilation of geographic information. As such it offers substantial advantages, but suffers from a general lack of quality assurance.
