woody_NA: Percent woody cover for North America

In rebeccalpowell/grassmapr: Predict C3/C4 Grass Distribution

Description

Gridded percent tree crown layer for North America in the year 2001, aggregated to 10' spatial resolution. Derived from the MODIS/Terra Vegetation Continuous Fields (v006) tree cover layer, following rules described in Powell et al. 2012.

Usage
