Just received this announcement from a colleague:



National Land Cover Database (NLCD 2001)
The U.S. Geological Survey, on behalf of the interagency Multi-Resolution Land Characteristics Consortium (MRLC), is pleased to announce the availability of NLCD 2001 products for the conterminous United States. These products are web enabled for download from the MRLC website at www.mrlc.gov. NLCD 2001 products include 21 classes of land cover, percent tree canopy and percent urban imperviousness at 30 m resolution derived from Landsat imagery. NLCD 2001 will support a wide variety of users, institutional sectors and local- to national-scale applications with this updated land-cover data. Alaska, Hawaii, and Puerto Rico will be completed by December of 2007, which will then represent the first compilation of nationwide land cover ever produced at 30-meter resolution.


Great news for a wide variety of applications - I was just looking at a watershed application, myself, where this data will fit quite nicely.

I did a quick check, it's not yet visible in the MRLC map viewer, however the data is available via FTP - visit the Multi-Resolution Land Characteristics site: http://www.mrlc.gov/
