Highlighting continued uncertainty in global land cover maps for the user community pub iis_env prog_esm In the last 10 years a number of new global datasets have been created and new, more sophisticated alorithms have been designed to classify land cover. GlobCover and MODIS v.5 are the most recent global land cover products available, where GlobCover (300 m) has the finest spatial resolution of other comparable products such as MODIS v.5 (50 m) and GLC-2000 (1 km). This letter shows that the thematic accuracy in the cropland domain has decreased when comparing these two latest products. This disagreement is also evident spatially when examining maps of cropland and forest disargeement between GLC-2000, MODIS and GlobCover. The analysis highlights the continued uncertainty surrounding these prducts, with a combined forest and cropland disagreement of 893 Mha (GlobCover versus MODIS v.5). This letter suggests that data sharing efforts and the provision of more 'in situ' data for training, calibration and validation are very important conditions for improving future global land cover products. 2011-10 published Institute of Physics Publishing (IOP) 10.1088/1748-9326/6/4/044005 XJ-11-171 [doi:10.1088/1748-9326/6/4/044005] 98 276 202 219 1631 119 public Environmental Research Letters 6 4 no.044005 44005 TRUE 1748-9326 European approach to GEOSS (EUROGEOSS, FP7 226487) Climate Change - Terrestrial Adaption and Mitigation in Europe (CCTAME, FP7 212535) Earth Observation for monitoring and assessment of the environmental impact of energy use (ENERGEO, FP7 226364) GLOBIOM FALSE yes info:eu-repo/grantAgreement/EC/FP7/226487/EU//EUROGEOSS; info:eu-repo/grantAgreement/EC/FP7/212535/EU//CCTAME; info:eu-repo/grantAgreement/EC/FP7/226364/EU//ENERGEO info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
