GlobCover 2009 (Global Land Cover Map)


European Space Agency Ionia GlobCover Portal (21.12.2010)
«The GlobCover Portal provides access to the results of the GlobCover project. GlobCover is an ESA initiative which began in 2005 in partnership with JRC, EEA, FAO, UNEP, GOFC-GOLD and IGBP. The GlobCover project has developed a service capable of delivering global composites and land cover maps using as input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. Currently, ESA makes available a set of products covering 2 periods: December 2004 - June 2006 and January - December 2009. Please see below the complete set of products and the time period that they cover.
The GlobCover composites are derived from the pre-processing module of GlobCover, which includes a set of corrections as cloud detection, atmospheric correction, geolocalisation and re-mapping. The GlobCover Land Cover map is compatible with the UN Land Cover Classification System (LCCS).»
