Tree Canopy

NLCD tree canopy cover is a 30 m raster geospatial dataset that is available for the conterminous United States, coastal Alaska, Hawaii, and Puerto Rico. These data contain percent tree canopy estimates, as a continuous variable, for each pixel across all land covers and types and are generated by the United States Forest Service (USFS). The USFS derives tree canopy cover from multi-spectral Landsat imagery and other available ground and ancillary information.  2011 and 2016 Forest canopy products are available for the Continental United States.  2011 products are available for Alaska, Hawaii, and Puerto Rico with 2016 products for these areas currently in production.
