Welcome to the European Space Agency Ionia GlobCover Portal


The GlobCover Portal provides access to the results of the GlobCover project. GlobCover is an ESA initiative in partnership with JRC, EEA, FAO, UNEP, GOFC-GOLD and IGBP. The GlobCover project has developed a service capable of delivering global composite and land cover maps using as input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. The GlobCover service has been demonstrated over a period of 19 months [December 2004 - June 2006], for which a set of MERIS Full Resolution (FR) composites (bi-monthly and annual) and a Global Land Cover map are being produced.
The GlobCover composites are derived from a set of processing made on the MERIS FR images such as cloud detection, atmospheric correction, geolocalisation and re-mapping. The GlobCover Land Cover map is compatible with the UN Land Cover Classification System (LCCS).

A set of GlobCover MERIS FR composites (Version 2) is available on the GlobCover Portal and can be downloaded from this website. This set includes:
- 10 bi-monthly reflectances composites for period December 2004 - June 2006
- 1 annual reflectance composite for year 2005

***The GlobCover Land Cover version V2.2 is now available HERE!***
The land cover product is available for download as a global mosaic and/or as a series of regional mosaics.
The maps are in geographic coordinates in a Plate-Caree projection (WGS84 geoid).
The new release clarifies the reported issues regarding the mapcode of some pixels by dividing the legend into global and regional.

GlobCover products distributed as torrent files


The GlobCover products for the Meris bi-monthly collection were successfully inserted in the Ionia GeoSpatial Catalogue, the respective torrent files were created and are ready to be seeded. The product download has started and it is now possible to participate in the collaborative effort to archive and distribute Earth Observation data. This image shows the spatial distribution of the seeding of the different tiles composing a GlobCover product. It reflects the actual state of the seeders and leechers for the Bi-Monthly product May/June 2005 and is updated each two hours
