Values
0-100 = percent tree canopy density per pixel

Data valid only within the biome. Please, refer to the biome boundary Shape file.

The MODIS-based Vegetation Continuous Field (VCF) layers provide 
estimates of global and regional vegetation cover for the study of 
biogeochemical cycles, ecosystem assessment, and land management. The 
VCF product depicts global sub-pixel estimates of vegetative components 
(tree cover, herbaceous cover, and bare cover) at 500m. The current 
dataset is a subset of the year 2000 VCF Collection 4 tree canopy cover 
layer for the boreal biome. 

MODIS data alone are inadequate for accurate forest cover area estimation. 
For forest cover and forest cover loss area calculation please use the 
calibrated products at 18.5 km resolution.
