The Science Daily site has up a piece on the effect user-generated content can have
on map-making. Scientists are appreciative of the data enthusiastic mappers can provide, updating maps on changes in local geographic information. "Goodchild's paper looks at volunteered geographic information as a special case of the more general Web phenomenon of user-generated content. It covers what motivates large numbers of individuals (often with little formal qualifications) to take part, what technology allows them to do so, how accurate the results are and what volunteered geographic information can add to more conventional sources of such information."
