CULTIVATED AREAS (USDA) --
Cultivated Areas, 2004 (1:100,000)
Shows percentage of cultivated land in homogeneous land-use areas.
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, nonagricultural 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.
Derived from National Agricultural Statistics Service, U.S. Department of Agriculture. This layer is exactly the same as a shapefile named "strata_a_in.shp" and titled "Stratification of Indiana 2004" that was acquired by personnel of the Indiana Geological Survey from the National Agricultural Statistics Service, U.S. Department of Agriculture. The shapefile was renamed and the title was changed in order to conform to metadata standards of the Indiana Geological Survey. Intended for geographic display and analysis at the state level.
