NLCD 2011 Land Cover (2011 Edition, amended 2014), 3 x 3 Degree: NLCD2011_LC_N36W090

Resource Abstract:
The National Land Cover Database products are created 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 (USFWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS).
The success of NLCD over nearly two decades is credited to the continuing collaborative spirit of the agencies that make up
the MRLC. NLCD 2011 is the most up-to-date iteration of the National Land Cover Database, the definitive Landsat-based, 30-meter
resolution land cover database for the Nation. The data in NLCD 2011 are completely integrated with NLCD 2001 (2011 Edition,
amended 2014) and NLCD 2006 (2011 Edition, amended 2014). For NLCD 2011, there are 5 primary data products: 1) NLCD 2011 Land
Cover 2) NLCD 2006/2011 Land Cover Change Pixels labeled with the 2011 land cover class 3) NLCD 2011 Percent Developed Imperviousness
4) NLCD 2006/2011 Percent Developed Imperviousness Change Pixels 5) NLCD 2011 Tree Canopy Cover provided by an MRLC partner
- the USDA Forest Service Remote Sensing Applications Center. In addition, ancillary metadata includes the NLCD 2011 Path/Row
Index shapefile showing the footprint of Landsat scenes and change analysis pairs used to derive 2006/2011 spectral change.
All Landsat scene acquisition dates are included in the shapefile's attribute table. As part of the NLCD 2011 project, NLCD
2001 and 2006 land cover and impervious data products were revised and reissued (2011 Edition, amended 2014) to provide full
compatibility with the new NLCD 2011 products. The 2014 amended version corrects for the over-elimination of small areas of
the four developed classes. NLCD Tree Canopy Cover was created using MRLC mapping zones from NLCD 2001 (see Tree Canopy Cover
metadata for additional detail). All other NLCD 2011 products were created on a path/row basis and mosaicked to create a seamless
national product. Questions about the NLCD 2011 land cover product can be directed to the NLCD 2011 land cover mapping team
at the USGS/EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.
