NOAA’s National Geodetic Survey (NGS) will host a summit to share information with other federal agencies on proposed improvements to the National Spatial Reference System (NSRS)—the coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States. Plans for the replacement of the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 1988) will be discussed, and the summit will help answer the following questions:
• What prompted the decision to modernize the horizontal and vertical geodetic datums?
• What methodologies will be used for modernizing the geometric and geopotential datums?
• How will these changes impact the user community?
• What tasks must be accomplished for the successful redefinition of the horizontal and vertical datums?
