NOTE: NLCD 2001 (2011 Edition) and NLCD 2006 (2011 Edition) products must be used in any comparison of NLCD 2001, NLCD 2006 and NLCD 2011 data products.

NLCD is re-releasing the 2011 product suite. The re-release contains a small change to only developed classes so that they directly align with the impervious products. Previous minimum mapping unit processing changed this direct link and the associated change comparisons in some areas. All products and eras have been harmonized and updated with a publication date of October 10, 2014.
