The "Biome Classification" product consists of a global map representing the global
distribution of the IGBP-biomes (biome classes discerned by the International Geosphere-Biosphere
Programme ) based on VGT images. The map was realised by application of a supervised decision
tree classifier on the 1km˛-resolution imagery of SPOT-VEGETATION of the year 1998/9. As a reference
data set for the calibration of the procedure we used the well-known DISCover-classification
which was derived by Loveland et al. (2000) from NOAA-AVHRR imagery of 1992/3. In this way,
the actual map should not be regarded as a new, stand-alone product but rather as an update of this
DISCover map.
There has been an ever-growing demand for actual information on the spatial distribution of the main
terrestrial ecosystems (biomes) because land cover is indeed a driving variable in many models for the
simulation and/or forecasting of weather, possible climate changes, carbon sequestration, erosion risk,
etc. - and actual biome maps form a valuable instrument for the verification of international environmental
treaties like the Kyoto-Bonn protocol.
