摘要：This paper explores the use of crowd sourced data on land cover. It compares data collectedthrough the Geo-Wiki system describing cropland land cover with cropland data recordedin global land cover datasets. Using an African case study, local confusion matrices are calculatedat discrete locations. At location the strongest correspondences are used to inferwhich global dataset best describes cropland at each location. Future research areas aresuggested.
