NGS Mission

To define, maintain and provide access to the National Spatial Reference System (NSRS) to meet our nation’s economic,

social, and environmental needs.

The NSRS is a consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States.

The NSRS SupportsNational Oceanic and Atmospheric AdministrationNSRS positioning data provides the reference for NOAA’s nautical charts, among many other geospatial applications.

Federal Emergency Management AgencyFEMA uses NSRS elevations to determine flood zones for the National Flood Insurance Program.

United States Army Corps of EngineersUSACE uses NSRS elevations to determine levee heights and positions in their Levee Safety Program.

United States Geological SurveyUSGS uses the NSRS to geospatially reference their Topographic maps and interior water data for the nation.

National Geospatial-Intelligence AgencyNSRS gravity data contributes to NGA’s geospatial mission.

Gravity for the Redefinition of the American Vertical Datum (GRAV-D)

New Datums are Coming in 2022!Both a new geometric and a new geopotential (vertical) datum will be released in 2022.

The realization of the new datums will be through GNSS receivers.

NGS will provide the tools to easily transform between the new and old datums.

The NGS mission remains the same
