National Geodetic Survey (NGS)
The mission of NOAA's National Geodetic Survey (NGS) is "to define, maintain and provide access to the National Spatial Reference System to meet our nation's economic, social, and environmental needs." NGS provides the framework for all positioning activities in the Nation. The foundational elements - latitude, longitude, elevation, shoreline information and their changes over time - contribute to informed decision making and impact a wide range of important activities including mapping and charting, navigation, flood risk determination, transportation, land use and ecosystem management. NGS' authoritative spatial data, models, and tools are vital for the protection and management of natural and manmade resources and support the economic prosperity and environmental health of the Nation.
