The U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program uses nationally consistent land cover to characterize environmental settings of stream and ground-water sampling sites. NAWQA uses areal weighting with mapped land cover to refine the spatial distribution of various quantitative data, especially nutrient inputs and pesticide applications, which originally are compiled by county. In 2005, NAWQA required nationally consistent land-cover data representing the early 2000s to indicate changes in urban/suburban land since the 1990s and to spatially allocate nutrient and pesticide data derived using the 2002 Census of Agriculture. The NLCDep0905 data set was compiled from data sources existing at that time as a stopgap measure to describe land cover in the early 2000s for NAWQA stream sampling sites until the USGS National Land Cover Database (NLCD) 2001 became available nationwide.
