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.
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 Connecticut was constructed in 1988
for use in 1989 and was based on 30-meter pixel resolution Landsat
imagery prints, 1:58000 NHAP Aerial Photos, 1:63360 County Highway
Maps, 1:100000 and 1:24000 topographic maps and JES surveys.
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.
