Summary

This tabular data set represents the percent of land cover classes from the 2006 National Land Cover Dataset compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "National Land Cover Database 2006" produced by the United States Geological Survey (Fry and others, 2011). Units are percent. The "National Land Cover Database 2006" (NLCD 2006) is a 16-class (additional four classes in Alaska only) land cover classification scheme that has been applied consistently [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the 2006 land cover for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
