NLCD 2016 USFS Tree Canopy Cover (CONUS)
The U.S. Forest Service tree canopy cover product is designed for the standard user who requires the single best representation of tree canopy designed for most applications. This product consists of a single percent tree canopy cover layer containing values ranging from 0 to 100 percent, with each individual value representing the area or proportion of that 30 m cell covered by tree canopy. The product is then filtered and masked to eliminate obvious non-tree areas, and to create a more cartographically useful product. Although this approach more closely resembles the NLCD 2001 tree canopy protocol, the products still used different mapping methods and are not designed to be directly comparable for change analysis. The percent tree canopy cover layer was produced using a Random Forests (trademarked by Leo Breiman and Adele Cutler) regression algorithm.
