National Geodetic Survey, formerly called the U.S. Coast and Geodetic Survey (U.S.C.G.S.), is a United States federal agency that defines and manages a national coordinate system. It measures the land and then draws maps. It also measures magnetic fields and tides. Congress started it in 1807 to draw maps of the coasts. It helps transportation and communication; mapping and charting; and many science and engineering uses. Since 1970, it has been part of the National Oceanic and Atmospheric Administration (NOAA), of the United States Department of Commerce.
