Volunteered GeographicInformation„

[...] the widespread engagement of large numbers of private citizens, often with little in the way of formal qualifications, in the creation of geographic information, a function that for centuries has been reserved to official agencies. They are largely untrained and their actions are almost always voluntary, and the results may or may not be accurate.

Goodchild, M. (2007): Citizens as sensors: The world of volunteered geography.

GeoJournal, 69, 211-221.
