“The response variables (canopy height and biomass) used in model development and validation were derived from the FIA database. Production of the NLCD 2001 and LANDFIRE projects was based on a mapping zone approach in which the conterminous U.S. is split into 66 ecoregionally distinct mapping zones.”
