What important function does the National Geodetic Survey group of NOAA perform?

The National Geodetic Survey (NGS), a division of NOAA, plays a crucial role in providing the foundational geodetic framework for the United States. This framework consists of a system of precise locations and elevation benchmarks that serve as reference points for various applications, including mapping, land surveying, and engineering projects. The NGS's work involves maintaining and improving the National Spatial Reference System (NSRS), which ensures that different geographic data can be accurately connected and compared across the country.

By overseeing this geodetic framework, the NGS supports various sectors like transportation, environmental monitoring, and emergency management, where accurate location data is vital. The NGS's activities ensure that both public and private entities are equipped with the necessary geospatial data to make informed decisions based on reliable geographic information.
