<dd>

The United States Department of Agriculture (USDA), National
Agricultural Statistics Service (NASS) area sampling frame is a
delineation of all parcels of land for the purpose of later sampling the
parcels.  The area frame is constructed by visually interpreting satellite
imagery to divide a state into homogenous land use areas (strata) based
on percent cultivated.  The strata are typically defined as low, medium or
high percent cultivated, non-agricultural land, urban use, agri-urban, or
water.  The boundaries of the strata usually follow identifiable features
such as roads, railroads and waterways.  The strata boundaries do not
coincide with any political boundaries, with the exception of state
boundaries.

The area sampling frame for Wisonsin was constructed for use in 2016
and was based on USGS 1:24,000 and 1:100,000 scale topographic maps,
1:250,000 scale Landsat imagery, and 1 meter resolution NAIP imagery.
Individual county files were merged into single statefile. The coordinates
for the strata polygons are unprojected to geographic latitude and longitude
(decimal degrees).  The spatial data file format is Environmental Systems
Research Institute's ArcMap 10.3 shapefile format. Gaps and overlaps were corrected
within and ESRI personal geodatabase.
