US, Land Cover


This layer contains the change in land cover classification for the US from 2001 to 2011. This raster file is intended for medium scale thematic mapping and analysis.



The spatial data were obtained from the National Land Cover Database (NLCD) provided by the Multi-Resolution Land Characteristics Consortium (MRLC). Attributes were modified to include pixel color and value information, opacity, and land cover type. The coordinate system of this data is WGS 1984.

"Land cover layer containing only those pixels identified as changed between NLCD 2001 Land Cover 2011 Edition and NLCD 2011 Land Cover products across the conterminous United States. This layer contains less overall change than the sum of 2001/2006 and 2006/2011 Land cover change pixels as some change transitioned through two classes from 2001 to 2006 to 2011. In this case, the latest change class is given" - MRLC
