Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This dataset provides a U.S. national 60-m, 19-class mapping of anthropogenic land uses for five time periods: 1974-1982-1992-2002-2012. The 2012 dataset is based on a slightly modified version of the National Land Cover Database 2011 (NLCD 2011) that was recoded to a schema of land uses, and mapped back in time to develop datasets for the four earlier eras. The time periods coincide with years in which U.S. Department of Agriculture (USDA) Census of [...]

Purpose

The purpose of this dataset is to serve as a consistent land use map product for five time periods between 1974 and 2012 for the conterminous U.S. The goal was to create a product which is (a) as consistent as possible with the NLCD 2001-2011 series, (b) agrees with other key data sources such as census-derived information, (c) uses a consistent method for all years, and (d) represents land use as accurately as possible. The focus of the product is to capture major land use trends.
