[dataset] Vegetation (Percent Tree Cover) - 2003

Percent Tree Cover represents the density of trees on the ground. The data show the ratio of the area covered with branches and leaves of trees (tree canopy) to the ground surface seen from the above (vertical direction). Satellite images of the whole globe from the MODIS sensor of Terra were used for the data creation. As for deciduous trees, which drop all their leaves during the period of low temperature or dryness, the ratio of the most flourishing period of a year (Maximum Percent Tree Cover) was referenced as the Percent Tree Cover.
