The U.S. Geological Survey released a Landsat-based report and dataset on anthropogenic land-use trends in the United States from 1974-2012. The time periods coincide with U.S. Department of Agriculture (USDA) Census of Agriculture data-collection years.

The work was completed as part of the USGS National Water-Quality Assessment (NAWQA) Program and termed the NAWQA Wall-to-Wall Anthropogenic Land Use Trends dataset. The associated datasets include five 60-meter geospatial rasters showing anthropogenic land use for the years 1974, 1982, 1992, 2002 and 2012; and 14 rasters showing the annual extent of timber clearcutting and harvest from 1999-2012.
