GlobCover
“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 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.”

"The U.S. Geological Survey (USGS) and the National Geospatial-Intelligence Agency (NGA) have collaborated in the development of a much improved global elevation model, the Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010). GMTED2010 replaces the widely used, 15-year-old GTOPO30 terrain model as the best available global digital elevation model." "Useful for regional-, continental-, and global-scale applications, GMTED2010 is derived from numerous higher quality elevation data sources that were unavailable at the time GTOPO30 was developed."
