New portrait of Earth shows land cover as never before
A new global portrait taken from space details Earth’s 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.
Earth’s 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.
The map is based on 20 Terabytes of imagery – equivalent to the content of 20 million books – acquired from May 2005 to April 2006 by Envisat’s Medium Resolution Imaging Spectrometer (MERIS) instrument.
All images then undergo a standardised processing technique developed and operated by Medias-France/Postel, together with Brockmann Consult, the Université catholique de Louvain and partners.
There are 22 different land cover types shown in the map, including croplands, wetlands, forests, artificial surfaces, water bodies and permanent snow and ice. For maximum user benefit, the map’s thematic legend is compatible with the UN Land Cover Classification System (LCCS).

The POSTEL Service Centre has produced the first global land cover map at
300m resolution. It discriminates the continental ecosystems in 22 classes
validated by independent experts.

It is a preliminary version that can be viewed with a zooming capacity
through the POSTEL web site at the address http://postel.mediasfrance.org/.

This land cover map is generated in the framework of the GLOBCOVER project,
an ESA funded initiative, using the data acquired between May 2005 and April
2006 by the MERIS sensor on-board the ENVISAT satellite.
