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 municipio boundaries (if needed, Puerto Rico only).

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 and overlaps within the state. This data set includes the area in square miles and number of acres for each strata. Boundaries may not be coincident with strata boundaries of adjacent states.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The sources used for digitizing strata boundaries are 1:24,000 scale Digital Raster Graphics and 0.5 meter resolution aerial imagery obtained from DigitalGlobe (see source below).

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 5.0
Horizontal_Positional_Accuracy_Explanation:

Not more than 10 percent of the test points shall be in error by more than 1/50 of an inch on original topo map.

Process_Step:

Process_Description:

The area sampling frame for Puerto Rico was constructed for use in 2022 and was based on USGS 1:24,000 and 1:100,000 scale topographic maps, 2010 Census Bureau TIGER data, 0.5 meter DigitalGlobe, Inc. aerial imagery, and 2010 Land Use Cover Layer. 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 ArcMap shapefile format. Gaps and overlaps were corrected within and ESRI personal geodatabase.
