MODERNIZATION OF THE NATIONAL SPATIAL REFERENCE SYSTEM
 
During the next decade, enhancements and additions to the network of Global Navigation
Satellite Systems (GNSS) such as the U.S. Global Positioning System, the Russian GLONASS,
European Union GALILEO and China's COMPASS will significantly improve the use of
space-based systems for surveying, mapping, charting, navigation and numerous other
applications. In order to meet the anticipated demands for an improved geospatial
framework that these developments will require, the National Geodetic Survey (NGS) is
implementing a plan for the modernization of the National Spatial Reference System (NSRS).
One of the significant elements of this plan calls for the adoption of an entirely new
horizontal and vertical datums to replace the North American Datum of 1982 (NAD 83), the
North American Vertical Datum of 1988 (NAVD 88) and various island vertical datums for
American Samoa, Guam, Northern Marianas, Puerto Rico and the U.S. Virgin Islands.
These new datums will be defined by a transition to be more closely aligned to the
International Terrestrial Reference Frame (ITRF) and to elevations based exclusively
on gravity observations. This presentation will highlight the rational for these changes,
the various elements that currently define NSRS and describe the activities to improve
the capacity of and access to NSRS in support this datum transition.
