A number of different remotely-sensed global land cover products are available but studies have shown that there are large spatial discrepancies between these different products when compared. To address this issue of land cover uncertainty, a tool called Geo-Wiki was developed, which integrates online and mobile applications, high resolution satellite imagery available from Google Earth, and data collection through crowdsourcing as a mechanism for validating and improving globally relevant spatial information on land cover and land use. Through its growing network of volunteers and a number of successful data collection campaigns, almost 5 million samples of land cover and land use have been collected at many locations around the globe. This paper provides an overview of the main features of Geo-Wiki, and then using a series of examples, illustrates how the crowdsourced data collected through Geo-Wiki have been used to improve information on land cover and land use. 2015-09 published Elsevier 10.1016/j.techfore.2015.03.002 XJ-15-173 [doi:10.1016/j.techfore.2015.03.002] 276 98 228 202 279 73 301 165 219 public Technological Forecasting and Social Change 98 324-335 TRUE 1873-5509 Operational Global Carbon Observing System (GEOCARBON, FP7 283080) Stimulating Innovation for Global Monitoring of Agriculture and its Impact on the Environment in support of GEOGLAM (SIGMA, FP7 603719) Harnessing the power of crowdsourcing to improve land cover and land-use information (CROWDLAND, FP7 617754) Exploring the potential for agricultural and biomass trade in the Commonwealth of Independent States (AGRICISTRADE, FP7 612755) Geo-Wiki FALSE yes info:eu-repo/grantAgreement/EC/FP7/617754/EU//CROWDLAND; info:eu-repo/grantAgreement/EC/FP7/603719/EU//SIGMA; info:eu-repo/grantAgreement/EC/FP7/283080/EU//GEOCARBON; info:eu-repo/grantAgreement/EC/FP7/612755/EU//AGRICISTRADE info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
