NGS (National Geodetic Survey)

The National Geodetic Survey (NGS) is a U.S. government agency responsible for mapping and measuring Earth's shape and size. They establish precise reference points called geodetic markers that help with accurate mapping, navigation, and surveying across the country. These measurements ensure that everything from GPS devices to construction projects can rely on consistent, accurate location data. NGS also updates and maintains the national coordinate system, supporting scientific research, infrastructure development, and environmental monitoring. Essentially, they create and maintain the geographic framework that keeps our maps, navigation, and spatial data precise and reliable.
