Description:
Abstract: The National Land Cover Database (NLCD) Land Cover Collection is produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium (www.mrlc.gov). The MRLC Consortium is a partnership of Federal agencies, consisting of the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service, the U.S. Forest Service, the National Park Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management, NASA, and the U.S. Army Corps of Engineers. A primary goal of the MRLC Consortium is to generate current, consistent, and seamless national datasets of land cover, percent developed imperviousness, and percent tree canopy. NLCD 2001 land cover was created by partitioning the conterminous United States into 66 mapping zones, based on ecoregion and geographical characteristics, edge matching features, and the size requirement of Landsat mosaics. NLCD 2001 represents a seamless assembly of land cover for all 66 MRLC mapping zones. NLCD 2001 land cover was developed for all 50 states and Puerto Rico / U.S. Virgin Islands. NLCD 2006 land cover was created on a path/row basis and mosaicked to create a seamless national product. NLCD 2006 land cover was developed for the conterminous United States. NLCD 2011 land cover was created on a path/row basis and mosaicked to create a seamless national product. The data in NLCD 2011 are completely integrated with NLCD 2001 and NLCD 2006. As part of the NLCD 2011 project, the NLCD 2001 and 2006 land cover data products were revised and reissued to provide full compatibility with the new NLCD 2011 products. NLCD 2011 land cover was developed for the conterminous United States and Alaska. Questions about the NLCD Land Cover Collection can be directed to the NLCD land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.
Purpose: The goal of this project is to provide the Nation with complete, current, and consistent public domain information on its land use and land cover.
