This coverage contains land-cover information for all of Ohio and portions of Indiana, Michigan, Kentucky, West Virginia, Pennsylvania, and New York. This dataset was derived from the U.S. Geological Survey's National Land Cover Dataset (NLCD). NLCD raster grids were downloaded from the USGS EROS Data Center web server at http://landcover.usgs.gov/natllandcover.html, by state. These grids were then reprojected, mosaiced and clipped against a polygon coverage representing the study area. Grid cell resolution is approximately 30 meters or 1 arc-second.
This coverage was created to derive land use and land cover characteristics for selected drainage basins within Ohio and portions of surrounding states for use in regression equations presented by Koltun (2003). For more information about the NLCD, see http://landcover.usgs.gov/.

Investigations Report 03-4164
The NLCD classification contains 21 different land-cover categories with a spatial resolution of 30 meters. The NLCD was produced as a cooperative effort between the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (USEPA) to produce a consistent, land cover data layer for the conterminous U.S. using early 1990s Landsat thematic mapper (TM) data purchased by the Multi-resolution Land Characterization (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies that produce or use land cover data. Partners include the USGS (National Mapping, Biological Resources, and Water Resources Divisions), USEPA, the U.S. Forest Service, and the National Oceanic and Atmospheric Administration. The National Land Cover Dataset was compiled from Landsat satellite TM imagery (circa 1992) with a spatial resolution of 30 meters and supplemented by various ancillary data (where available). The analysis and interpretation of the satellite imagery was conducted using very large, sometimes multi-state image mosaics (i.e. up to 18 Landsat scenes).

An accuracy assessment is done on all NLCD on a Federal Region basis
following a revision cycle that incorporates feedback from MRLC
Consortium partners and affiliated users. The accuracy assessments
are conducted by private sector vendors under contract to the USEPA.
A protocol has been established by the USGS and USEPA that incorporates
a two-stage, geographically stratified cluster sampling plan (Zhu et
al., 1999) utilizing National Aerial Photography Program (NAPP)
photographs as the sampling frame and the basic sampling unit. In
this design a NAPP photograph is defined as a 1st stage or primary
sampling unit (PSU), and a sampled pixel within each PSU is treated
as a 2nd stage or secondary sampling unit (SSU).
PSU's are selected from a sampling grid based on NAPP flight-lines and
photo centers, each grid cell measures 15' X 15' (minutes of
latitude/longitude) and consists of 32 NHAP photographs. A geographically
stratified random sampling is performed with 1 NAPP photo being randomly
selected from each cell (geographic strata), if a sampled photo falls
outside of the regional boundary it is not used. Second stage sampling
is accomplished by selecting SSU's (pixels) within each PSU (NAPP photo)
to provide the actual locations for the reference land cover
classification.
The SSU's are manually interpreted and misclassification errors are
estimated and described using a traditional error matrix as well as a
number of other important measures including the overall proportion of
pixels correctly classified, user's and producer's accuracies, and
omission and commission error probabilities.
At the time of CD release (Spring, 2001), the accuracy assessment was not
complete. For Region VI accuracy assessment please check the NLCD
Website: http://edcwww.usgs.gov/programs/lccp/natllandcover.html.
The accuracy assessment numbers will be posted there when available.
An in-depth accuracy report has been completed form WV, KY, NY, and PA. The
results are available at http://landcover.usgs.gov/accuracy/.
Not required for raster data
Source dataset was originally in meters. The new grid was created with elevations in decimeters
Each Landsat Thematic Mapper image used to create the NLCD was precision terrain-corrected using 3-arc-second digital terrain elevation data (DTED), and georegistered using ground control points. This resulted in a root mean square registration error of less than 1 pixel (30 meters).
NLCD grids for Ohio, Michigan, Indiana, Kentucky, West Virginia, Pennsylvania, and New York were downloaded from http://landcover.usgs.gov/natllandcover.html. Grids were copied into a single workspace, and mosaic'd in ARC/GRID 8.0.2. Resulting grid was then clipped against a polygon coverage representing the study area. Resulting grid was then projected from:
