Tree Cover Continuous Fields

Data Access
ESDI
Overview
aster

Representation of vegetation land cover into a limited number of classes (such as "grassland", "forest", "urban", etc.) does not account for internal variability, nor do distinct classes recognize transition zones between adjacent cover types. Because of this, an alternative paradigm to describing land cover as discrete classes is offered in this 1 Kilometer Tree Cover Continuous Fields product, where vegetation is represented as continuous fields of land cover, resulting in every pixel having a percentage value for tree cover.

Code Values
Value Label
10-80 Percent tree cover, where 10% is low and 80% is high
254 Non-vegetated
255 Tree cover is less than 10%
