The 1970 National Atlas of the United States of America
Adapted from "About The National Atlas of the United States of America," by the U.S. Geological Survey
The National Atlas of the United States of America was published in 1970. It was designed to be of practical use to decision makers in government and business, and for planners and research scholars as well as others needing to visualize country-wide distributional patterns and relationships between environmental phenomena and human activities. The National Atlas represents the principal characteristics of the country in 1970, including its physical features, historical evolution, economic activities, sociocultural conditions, administrative subdivisions, and place in world affairs.
Various federal agencies, professional organizations, and commercial firms had advocated producing a National Atlas of the United States of America, but the magnitude of the task and the scope of the research required deterred those who would begin it. Late in 1954, the National Academy of Sciences-National Research Council established a Committee on the National Atlas of the United States, with representatives from several federal mapmaking agencies. The committee's primary responsibilities were to coordinate all federal agencies that would be involved in producing the atlas and to ensure uniform quality in its cartography. This proved to be a nearly impossible task, and consequently in 1961 the committee terminated itself. In so doing it recommended that the atlas be completed by one federal agency, preferably the Geological Survey in the U.S. Department of the Interior. In March of 1961, the Secretary of the Interior accepted the challenge.
Congress appropriated funds to begin work on the National Atlas in 1963, and on reimbursable loan the Library of Congress made available the chief of its Geography and Map Division, Dr. Arch C. Gerlach, to serve as editor. Eighty-four agencies and bureaus appointed liaison officers to the National Atlas Project, base maps were prepared at four scales, and an advisory group of eminent cartographers and geographers collaborated to formulate fundamental design principles and specifications.
The first part of the National Atlas is devoted to general reference maps that contain most of the forty-one thousand place names recorded in the index. These maps were included for the convenience of readers wanting basic locational information. In the thematic section of the National Atlas, separate subdivisions deal with the country's physical, historical, economic, and socio-cultural characteristics. The maps in this portion of the atlas represent the relationships between human beings and their environment while offering scientific bases for analyzing the nation's economic development in 1970. The National Atlas proved to be the last paper atlas of this magnitude produced by the federal government.
In 1997, work began on a new and innovative National Atlas. The new edition included both electronic and paper map products and exploits information presentation, access, and delivery technologies that did not exist in 1970. The new National Atlas was intended to provide a comprehensive, map-like view into the enormous wealth of data collected by the U.S. government. It offered an authoritative scientific, social, and historical information; easy-to use online interactive maps; and tools to display, manipulate, and query its data so that users can produce their own analyses. Above all, the National Atlas is a showcase for the geospatial data collected by federal agencies. In 2014, the online version of the National Atlas was replaced by a newer online platform which was renamed the National Map.
