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.
Purpose:
These data are intended for geographic display and analysis at the state
level. The data should be displayed and analyzed at a scale of
1:100,000 or smaller (e.g., 1:250,000, etc.). The strata data are
provided "as is". USDA/NASS does not warrant results you may obtain
using the strata data.

Process_Step:
Process_Description:
The area sampling frame for Minnesota was constructed for use in 2009
and was based on USGS 1:24,000 and 1:100,000 scale topographic maps,
1:250,000 scale digital Landsat imagery, and 1 and 2 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 ArcView shapefile format.
The shapefile was checked and edited for topology in 1998. Gaps and
overlaps were corrected within and ESRI personal geodatabase.
