The intent of this document is to provide to the public the current status of plans by the National Geodetic Survey (NGS) to modernize the National Spatial Reference System (NSRS). This particular document covers the Geopotential component; that is, the definition and determination of orthometric heights, geoid undulations, gravity, deflections of the vertical, geopotential numbers, and any other quantity directly related to the geopotential field of the Earth. Many abbreviations and terminology specific to the new geopotential datum are used in this document. As a convenience to the reader they are defined in the glossary at the end of the document.
