The USGS acknowledges the support of Space Imaging and the Kentucky Landscape Initiative (KLI) in development of data in this zone.
The NLCD 2001 was created by partitioning the U.S. into mapping zones. A total of 66 mapping zones were delineated within the conterminous U.S. based on ecoregion and geographical characteristics, edge matching features and the size requirement of Landsat mosaics. Mapping zone 53 encompasses whole or portions of several states including the states of Tennessee, Kentucky, Ohio, West Virginia, and Virginia . Questions about the NLCD mapping zone 53 can be directed to the NLCD 2001 land cover mapping team at the National Center, EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.
Acquisition dates of Landsat ETM+ (TM) scenes used for land cover classification in this zone are as follows:
