Description: USGS National Atlas provides a comprehensive, maplike view into the enormous wealth of geospatial and geostatistical data collected for the United States. The Atlas includes authoritative national geospatial and geostatistical data sets. Examples of digital geospatial data include soils, county boundaries, volcanoes, and watersheds. Crime patterns, population distribution, and incidence of disease are examples of geostatistical data. This information is tied to specific geographic areas and is categorized and indexed using different methods, such as county, State, and zip code boundaries or geographic coordinates like latitude and longitude. Maps include links to related sites on the Internet for more up-to-date, real-time, and regional data information. Also see The National Map , providing high-quality, geospatial data from the USGS.
