 AC9229.The horizontal coordinates were established by GPS observations
 AC9229.and adjusted by the National Geodetic Survey in February 2007.
 AC9229
 AC9229.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007).
 AC9229.See National Readjustment for more information.
 AC9229.The horizontal coordinates are valid at the epoch date displayed above.
 AC9229.The epoch date for horizontal control is a decimal equivalence
 AC9229.of Year/Month/Day.
 AC9229
 AC9229.The orthometric height was determined by GPS observations and a
 AC9229.high-resolution geoid model.
 AC9229
 AC9229.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AC9229
 AC9229.The Laplace correction was computed from DEFLEC09 derived deflections.
 AC9229
 AC9229.The ellipsoidal height was determined by GPS observations
 AC9229.and is referenced to NAD 83.
 AC9229
 AC9229.The geoid height was determined by GEOID09.
