> 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.
