Description:

Abstract:

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.

Though all of the dates for this frame point to 2005, this is only when the older frame from the paper map was converted over to digital form. All of the stratification work for the paper maps and was completed in 1984.

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_Description:

The area sampling frame for Colorado was constructed for use in 2005 and was based on USGS 1:24,000 and 1:100,000 scale topographic maps, 1:250,000 scale digital Landsat imagery, and 2 meter resolution NAPP 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. Gaps and overlaps were corrected within and ESRI personal geodatabase.

Though all of the dates for this frame point to 2005, this is only when the older frame from the paper map was converted over to digital form. All of the stratification work for the paper maps and was completed in 1984.
