National Geodetic Survey
The US National Geodetic Survey ( NGS ) is a geodesy organization subordinated to the US government , which is responsible for national surveys within the USA. It has been part of the National Oceanic and Atmospheric Administration (NOAA) since 1970 and is based in Silver Spring , Maryland.
The National Geodetic Survey (s) also oversees various research agendas , including in the area of reference systems , time services , geoid determination and satellite geodesy . In the basic forms of division between federal and state agendas, there are similarities to the German system ( land surveying offices and BKG ), while other states know surveying as the task of the central administration.
