Purpose

To provide complete, current, and consistent public domain information of national land use and land cover. This national (conterminous United States) data set was developed for use by the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. NAWQA uses land-use data to assess land-use change, such as urban development and loss of agricultural lands as well as to allocate nutrient and pesticide loads to particular land-use categories.
