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.

Data_Quality_Information: Logical_Consistency_Report: Checks for topological consistency were performed on this data set. Completeness_Report: There are no known gaps or missing data. This data set includes the area in square miles and number of acres for each strata. Because the area sampling frame strata boundaries are modified (i.e., not a new area sampling frame), the boundaries may not be coincident with strata boundaries of adjacent states.

The boundaries were modified in 2001 to conform to USGS 1:100,000 scale topographic digital raster graphics, TIGER 2000 digital files, and Landsat 5 and 7 Thematic Mapper imagery. Individual county files were merged into single state file. 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.
