Introduction
GlobCover is an ESA initiative which began in 2005 in partnership with JRC, EEA, FAO, UNEP, GOFC-GOLD and IGBP. The aim of the project was to develop 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. ESA makes available the land cover maps, which cover 2 periods: December 2004 - June 2006 and January - December 2009. See more at: http://due.esrin.esa.int/globcover/
There is a validation report available at: http://due.esrin.esa.int/globcover/LandCover2009/GLOBCOVER2009_Validation_Report_2.2.pdf
Coverage
This dataset has a global coverage (except for the arctics). It is based on a 300 m x 300 m grid.
Legends
The Globcover dataset has 23 different categories that EMD has mapped in to a suggest roughness length, z0.
