Digital map file of major land uses in the United States

Each state report contains a map of the state's major land uses and, where possible, discusses the influence of land use on water quality in the state. This is a polygon coverage of major land uses in the United States.

The source of the coverage is the map of major land uses in the 1970 National Atlas of the United States, pages 158-159, which was adapted from U.S. Department of Agriculture, "Major Land Uses in the United States," by Francis J. Marschner, revised by James R. Anderson, 1967.
