The National Geodetic Survey Improves the National Spatial Reference System with Simultaneous Major Product Releases
In the first week of July, NOAA’s National Geodetic Survey (NGS) released the results of three major improvements to the National Spatial Reference System (NSRS). The NSRS is the consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States and its territories. NGS maintains and provides access to the NSRS, which is the foundation for the nation’s transportation, mapping, and charting infrastructure and serves a multitude of scientific and engineering applications.
The three improvements to the NSRS are:
- A new realization of the North American Datum of 1983 (NAD 83);
- New gravimetric and hybrid geoid models; and
- The determination of updated elevations in the Gulf Coast Height Modernization Project.
