NLCD, clipped to show just the county, with the shapefile TIGER overlaid, for 1992, 2001, 2006, and 2011. NLCD 2001 Land Cover (CONUS) The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released four National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, and 2011. The Multi-Resolution Land Characteristics Consortium has supported the development of two national digital land cover products: the National Land Cover Dataset (NLCD) 1992 and National Land Cover Database (NLCD) 2001. The NLCD 2001 maps 16 land-cover classes across the conterminous United States at a nominal pixel scale of 30-m × 30-m with a minimum mapping unit of 5 pixels (see Homer et al., 2004, Homer et al., 2007 for full details of the classification procedures).Stehman et al. NLCD 2016 represents the latest evolution of NLCD land cover products focused on providing innovative land cover and land cover change data for the Nation. The primary source data were bands 3, 4, 5, and 7 (visible red, near-infrared, mid-infrared, and thermal infrared) of cloud-free Landsat TM scenes acquired during the spring and fall (when trees are mostly bare of leaves) of 1992. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016. The 1992/2001 NLCD Land Cover Change Product was developed to offer a more accurate and useful guide to change analysis than can be provided by direct comparison of NLCD 1992 with NLCD 2001. NLCD 2016 now offers land cover for years 2001, 2003, 2006, 2008, 2011, 2013, 2016, and impervious surface for 2001, 2006, 2011, and 2016. NLCD 2016 offers 7 integrated epochs of land cover for years 2001, 2003, 2006, 2008, 2011, 2013, and 2016. For the NLCD 2001 Alaska land cover classification, the overall thematic accuracy was 83.9 percent at Anderson Level I and 76.2 percent at Anderson Level II (Selkowitz and Stehman, 2011).
