These scenes range in dates as follows: path/row date scene id 10/29 10/02/2001 7010029000127550 11/27 10/04/2002 (L5) 5011027000227710 11/28 10/01/2001 (L5) 5011028000127410 11/29 10/22/2000 7011029000029650 12/27 09/30/2001 7012027000127351 12/28 09/30/2001 7012028000127351 12/29 10/16/2001 7012029000128950 12/30 10/16/2001 7012030000128950 13/29 10/12/2000 (L5) 5013029000028610 13/30 11/08/2001 7013030000029450 14/29 10/12/2003 (L5) 5014029000328510 11/29 cloud patch Dates indicated by (L5) are from LandSat 5, others from LandSat 7. This dataset includes the 6 30m bands - 3 visible and 3 infrared. This is part of a 3-image set used to derive the landcover, imperviousness, canopy, and change data in the NLCD/CCAP 2001 project. These images also drive the thematic classification for the MELCD 2004 landcover and imperviousness data, combined with 2004 SPOT-5 data for more spatial detail. The NLCD/CCAP 2001 (National LandCover Dataset/Coastal Change Assessment Program) is a combined USGS and NOAA project to update and improve the original NLCD and CCAP data (circa 1992). Purpose: To derive landcover, imperviousness, and forest canopy for NLCD 2001 and MELCD 2004 projects.
