A new global portrait taken from space details Earths land cover with a resolution never before obtained. ESA, in partnership with the UN Food and Agriculture Organisation, presented the preliminary version of the map to scientists last week at the 2nd GlobCover User Consultation workshop held in Rome, Italy.

Earths land cover has been charted from space before, but this map, which will be made available to the public upon its completion in July, has a resolution 10 times sharper than any of its predecessors.

Scientists, who will use the data to plot worldwide land-cover trends, study natural and managed ecosystems and to model climate change extent and impacts, are hailing the product generated under the ESA-initiated GlobCover project as 'a milestone.'

"The GlobCover system is a great step forward in our capacities to automatically produce new global land cover products with a finer resolution and a more detailed thematic content than ever achieved in the past," Frdric Achard of the European Commission's Joint Research Centre (JRC) said.

"This GlobCover product is much more than a map. It is an operational scientific and technical demonstration of the first automated land cover mapping on a global scale and may provide the detailed description of the land surface states needed for regional climate modelling," said Prof. Pierre Defourny, from the Universit catholique de Louvain, who designed the land classification process.

"Land cover data is an essential requirement of the sustainable management of natural resources, environmental protection, food security, climate change and humanitarian programmes," John Latham of the Food and Agriculture Organisation (FAO) said.

"The GlobCover product will be the first freely available product at 300m resolution and is therefore a milestone product which will be fundamental to a broad level stakeholder community."
