U.S. Geological Survey, 2005, 1970's Land use data refined with 2000 population data to indicate new residential development for the conterminous United States: U.S. Geological Survey data release, https://doi.org/10.5066/P9REKMFH.

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 data set represents U.S. Geological Survey (USGS) historical Land Use and Land Cover (LULC) from the 1970's that has been refined with 2000 population density at the block group level to indicate new residential development representative of the early 2000's. Any area having a population density of at least 1,000 people per square mile had been re-classified as "urban" land in this data set.

Purpose

This is one of the ancillary GIS (geographic information system) data layers developed to characterize USGS National Water-Quality Assessment (NAWQA) sampling sites and study areas for national synthesis of water-quality data. For background on the design of the NAWQA program see Gilliom and others (1995).
