The USGS acknowledges the support of NOAA in development of data in this zone. http://ecos.fws.gov/ServCatFiles/reference/holding/15974/NRPC_Padilla2013_NWRSLandCover.gdb.zip The Natural Resources Program Center conducted a land cover analysis to determine land cover types, acres and their subsequent percentages for the National Wildlife Refuge System. The National Land Cover Database (NLCD) 2001 was used to determine land cover classes and calculate number of acres at national and regional scales. Coordination Areas, National Wildlife Refuges, Wildlife Management Areas and Waterfowl Production Areas were extracted from the U.S. Fish and Wildlife Service interest boundary. Excluding Hawaii and Puerto Rico, other pacific and Caribbean were not included in the analysis due to absence of land cover data in the area. The FwsInterest feature class is an aggregated data layer derived by appending separate regional feature data sets into a single national set. The spatial and positional accuracy of this information will vary depending on the original source data and methods utilized. For additional details on FWS boundary data refer to http://www.fws.gov/GIS/data/CadastralDB/index.htm. The NLCD layer was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. It was developed for the United States at medium spatial resolution. This landcover map and all documents pertaining to it are considered "provisional" until a formal accuracy assessment can be conducted. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2004) and http://www.mrlc.gov/mrlc2k.asp. National Land Cover Database (NLCD 2001) was used to determine land cover classes and acres for the National Wildlife Refuge System. The original NLCD coverage was clipped to refuges within each US Fish and Wildlife Service Region. 19850605 20060728 Ground Condition for NLCD Complete Unknown -160.324461 -155.204867 22.291669 18.834501 ISO 19115 Category imagery Earth Cover Base Maps BGDS None Land Cover digital spatial data GIS NWRS U.S. Department of Commerce, 1995, Countries, dependencies, areas of special sovereignty, and their principal administrative divisions, Federal Information Processing Standard 10-4,): Washington, D.C., National Institute of Standards and Technology U.S. United States Continental US Hawaii Puerto Rico Alaska None The digital land cover dataset may be used for various purposes with user's discretion.

Other topological erros were not counted for. The information on data quality for mapping NLCD was generated by the Decision Tree algorithm that conducts a cross-validation for assessing classification and prediction reliability. FwsInterest is a dynamic data layer, updates and revisions are ongoing. The landcover map is considered "provisional" until a formal accuracy assessment is completed.

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 (USDA), the U.S. Forest Service (USFS), 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 2001 for the United States at medium spatial resolution. This landcover map and all documents pertaining to it are considered "provisional" until a formal accuracy assessment can be conducted. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2004) and http://www.mrlc.gov/mrlc2k.asp. The NLCD 2001 is created by partitioning the U.S. into mapping zones. A total of 66 mapping zones within the conterminous U.S., with an additional 13 in Alaska, were delineated based on ecoregion and geographical characteristics, edge matching features and the size requirement of Landsat mosaics.

It may also include inholdings that are not administered by USFWS. The primary source for this information is the USFWS Realty program. The FwsInterest feature class is an aggregated data layer derived by appending separate regional feature data sets into a single national set. The spatial and positional accuracy of this information will vary depending on the original source data and methods utilized. Data sources are not listed in this document but are maintained for each region and can be requested. We strive to improve the accuracy of this data and incorporate more reliable information when available. Coordination Areas, National Wildlife Refuges, Wildlife Management Areas and Waterfowl Production Areas were extracted from the U.S. Fish and Wildlife Service interest boundary. The NLCD 2001 was clipped to the selection from the FWS Interest boundary. Clip processing was done by each FWS region. 20130201 Raster Grid Cell Albers Conical Equal Area 8.0 18.0 -157.0 3.0 0.0 0.0 coordinate pair 0.00000000499320584879115 0.00000000499320584879115 meter D WGS 1984 WGS 1984 6378137.0 298.257223563 VAT_NLCD NLCD Land Cover Layer National Land Cover Database 2001 ObjectID Internal feature number ESRI Sequential unique whole numbers that are automatically generated.
