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. This site provides links to download ESRI shape and symbology layer files, as well as low resolution JPEG or higher resolution PDF images for each state.

The Cost of Pollination survey, conducted annually in all 50 states, collects information on acreage pollinated, colonies used, and dollars spent for a variety of 33 different crops. The target population for Cost of Pollination estimate program is all farms and ranches with at least one acre of a crop determined to be potentially pollinated by honey bees (Apis). Includes current and previous year data on cost of pollination as downloadable zipped CSV files for crop categories Tree Nuts, Tree Fruit, Citrus, Melons, Berries, Other fruit, Vegetables, and Other crops, detailing Paid Pollinated Acres, Price per Acre, Colonies Used, Price per Colony, and Total Value of Pollination by region.

The Census of Agriculture provides a detailed picture every five years of U.S. farms and ranches and the people who operate them. Conducted by USDA's National Agricultural Statistics Service, the 2012 Census of Agriculture collected more than six million data items directly from farmers. The Ag Census Web Maps application makes this information available at the county level through a few clicks. The maps and accompanying data help users visualize, download, and analyze Census of Agriculture data in a geospatial context.
