National Land Cover Database 2001 (NLCD2001)

Product Data Downloads

Generation of NLCD2006 products helped to identify some update issues in the NLCD 2001 land cover and percent developed imperviousness products only. These issues were evaluated and corrected, necessitating a reissue of NLCD2001 land cover and percent developed imperviousness products (NLCD2001 Version 2.0) as part of the NLCD2006 release. There is no NLCD2001 Version 2.0 for percent tree canopy.

NOTE: NLCD2001 Version 2.0 products must be used in any comparison of NLCD2001 and NLCD2006 data products.
