MERIS
Download:
 HI-RES JPEG (Size: 1758 kb)  HI-RES PNG (Size: 4977 kb)
A mosaic of global land cover from Envisat's MERIS instrument. The same sensor is to be used as the basis of ESA's GLOBCOVER project to creating the most detailed land cover map ever. For this mosaic a total of 1561 orbits taking place over the period May, July, October and November 2004 have been used to screen the clouds. The colour composite has been obtained by merging MERIS spectral bands 2, 3, 5, 7.

GLOBCOVER comparison
Download:
 HI-RES JPG (Size: 760 kb)  HI-RES TIFF (Size: 1129 kb)
This chart is a comparison of different mosaics of the same site in Siberia acquired using the 30-metre spatial resolution Landsat ETM+, the around ten times greater resolution MERIS and the 1-km resolution SPOT 5 VGT. What is clear is that MERIS delivers a level of detail closer to the former than the latter, making it a useful basis for the GLOBCOVER mapping project.

GLC 2000

 HI-RES JPG (Size: 871 kb)  HI-RES TIFF (Size: 4851 kb)
The Joint Research Centre of the European Commission previously produced the one-km-resolution Global Land Cover 2000 (GLC 2000) map produced from SPOT 5 Vegetation Instrument data for the year 2000. The new global land cover maps produced during ESA's GLOBCOVER will be compatible with GLC 2000, serving as an update.
