National Land Cover Data 2001
This data set is one complete raster coverage of the MRLC
National Land Cover Data (NLCD) covering the conterminous United States.
The NLCD is composed of 16-classes, and is derived from

Please note: the 1992 NLCD data are also available.
The NLCD data is distributed by the Multi-Resolution Land Characteristics Consortium (MRLC). CDIAC has combined the regional files created by the MRLC into one contiguous raster data file for the conterminous United States. Smaller, regional coverages can be downloaded directly from the MRLC: http://www.mrlc.gov/nlcd_multizone_map.php
