National Geodetic Survey National Geodetic Survey, formerly called the 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 1970, it has been part of the National Oceanic and Atmospheric Administration (NOAA), of the Department of Commerce. The original predecessor agency of the NGS was the United States Coast Survey, created by Congress in 1807 to conduct a "Survey of the Coast". This organization represented the Jefferson administration's interest in science and stimulation of international trade. The Jackson administration expanded and extended the coast surveys scope and organization.:468 Progress moved ahead slowly and haltingly during the first 25 years. Not until August 29, 1811, did F. R. Hassler sail for Europe to purchase the proper instruments. He remained in Europe during the War of 1812, and then he returned to the United States, arriving on August 16, 1815. Hassler's plan was to employ triangulation to establish his system. Work began in the vicinity of New York City in 1816. The first baseline was measured and verified in 1817. A further Act of Congress in 1818 interfered with Hassler's work. The Army and Navy were placed in charge of the survey work. This generated a lull in activity which lasted from 1818 to 1832. The Coast survey existed without a superintendent during the 14 years from 1818 to 1832. Little work was carried out until another Federal law was enacted on July 10, 1832.
