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.

The shapefile was converted (digitized) from paper to digital using mosaiced 1:100,000 scale topographic raster data and vector DLG data. Individual county strata files were merged (dissolved) by strata into a single state strata file. The coordinates for the strata polygons were projected to UTM zone 18 (meters), WGS 1984 datum. The spatial data file format is Environmental Systems Research Institute's ArcView shapefile format.
