The USGS acknowledges the support of Space Imaging LLC 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 51 encompasses whole or portions of several states including the states of Michigan, Wisconsin, Ohio, and Indiana. Questions about the NLCD mapping zone 51 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:
