AbstractNational Land Cover Database (NLCD) 2016 Tree Canopy Cover, produced by MRLC (Multi-Resolution Land Characteristics) Consortium. This dataset is part of the updated 2016 release of the larger National Land Cover Database (NLCD) that also includes information on land cover, percent imperviousness, and percent shrub/grass. The NLCD provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. Percent tree canopy cover is a measure of local tree density that has a variety of applications in wildlife habitat analysis, fire behavior modeling, carbon accounting, and hydrologic analysis. Using medium spatial resolution imagery (30m) from Landsat, MRLC produced consistent, seamless per-pixel estimates of percent tree canopy cover ranging from 0 to 100 percent.

Full metadata are included in the nlcd16tr.img.xml file located in the same path as the maintenance format file.

Known errors/qualifications1. Since new 2016 versions of NLCD products for all years have now been released, the decision was made to refrain from reprojecting this dataset into the County's standard NAD83 HARN projection. Since pixels were therefore not resampled, they do now represent the exact area on the ground that the original satellite sensor collected.
