context_page_description: The National Geodetic Survey, formerly the United States Survey of the Coast, United States Coast Survey, and United States Coast and Geodetic Survey, is a United States federal agency that defines and manages a national coordinate system, providing the foundation for transportation and communication; mapping and charting; and a large number of applications of science and engineering. Since its foundation in its present form in 1970, it has been part of the National Oceanic and Atmospheric Administration, of the United States Department of Commerce.
  The National Geodetic Survey's history and heritage are intertwined with those of other NOAA offices. As the U.S. Coast Survey and U.S. Coast and Geodetic Survey, the agency operated a fleet of survey ships, and from 1917 the Coast and Geodetic Survey was one of the uniformed services of the United States with its own corps of commissioned officers. Upon the creation of the Environmental Science Services Administration in 1965, the commissioned corps was separated from the Survey to become the Environmental Science Services Administration Corps.
