This raster layer is a georeferenced image containing tree canopy data for Alaska, in an Albers Equal-Area Conic projection and at a resolution of 100 meters. The tree canopy data were derived from the 2001 National Land Cover Database (NLCD) Percent Tree Canopy data set, a product of the Multi-Resolution Land Characteristics Consortium (MRLC). The MRLC is a multi-agency cooperative effort to study land cover change. This layer is part of the 1997-2014 edition of the National Atlas of the United States.The 100-meter resolution tree canopy data were developed to portray the tree canopy of the United States at 1:1,000,000 scale. They are intended primarily for visual purposes. The original NLCD data should be used for conducting scientific analysis.
