Abstract | National Land Cover Database 2011 U.S. Forest Service Tree Canopy cartographic product. It consists of a single layer, percent tree canopy cover, with file pixel values ranging from 0 to 100 percent, with each individual value representing the area or proportion of that 30-meter 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. It was produced using a Random Forests (trademarked by Leo Breiman and Adele Cutler) regression algorithm. Full metadata are included in the nlcd11tr.img.xml file located in the same path as the maintenance format file. -- See more information. | |
