Land cover classes
LCCS as the framework
Starting point:• Tree cover• Shrubs• Mosaic• Other vegetated land• Burnt area• Non-vegetated land• Water• No data including cloud cover
Land use classes
Forest
Other wooded land
Other land with tree cover
Grassland/range/herbaceous
Agricultural crops
Built-up area
Other non-vegetated areas
Water
No data
Implementation
• Common framework and classification system
• High degree of flexibility
• Involvement of national teams
• Support to countries

Expected outputs
Regional, biome and global trends related to forests 1975-1990-2000-2005:
• area change statistics• information on land use dynamics
Forest maps
A framework to support further monitoring of forests, land use and the environment
Baseline data for research, modeling...
