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.[1] 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.[1]
