Graphic image of NLCD 2001 data.


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 Landsat 7 Enhanced Thematic Mapper, and Landsat 5 satellite data centered around 2001. A complete description of these data can be found at

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:
