Land Use Strata

The USDA-NASS area sampling frame delineates all parcels of land for the purpose of sampling. The area frame is constructed by visually interpreting satellite imagery to divide a state into stratification classes (strata) based on percent of land used in cultivation. Strata are typically defined by percent cultivated, non-agricultural land, urban use, agri-urban, or water.
