Description: The National Land Cover Database 2011 land cover layer for Alaska was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture - Forest Service (USDA-FS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land Cover Database (NLCD) circa 2011 for the United States at medium spatial resolution. This land cover map and all documents pertaining to it are considered "provisional" until a formal accuracy assessment can be conducted. The NLCD 2011 Alaska was created by using 44 path/row strips and comparing to the original 2001 imagery. Change between these images was applied to the original 2001 land cover in the original 13 Alaska mapping zones to create 2011 Alaska land cover. Questions about NLCD mapping zones can be directed to the NLCD land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or email@example.com.Landscape dynamics source for NPS Inventory and Monitoring national protocol.
