      Nov 14, 2003 · The first method approximates NAVD88 Heights by applying geoid heights to the measured ellipsoid heights using the equation H=h-N (Orthometric Height = Ellipsoid Height - Geoid Height). The accuracy of this method when applying the NGS Geoid 2012A to NAD83(2011) 2010.00 Epoch ellipsoid heights in San Francisco is approximately 0.06 meters as ...

      The NAVD88 orthometric height of this benchmark determined by spirit leveling is 1694.931 meters and differs from its calculated dynamic height by 1.696 meters. However, using the same formula and the same geopotential number, but divided by a gravity value derived from the Helmert height reduction formula, the result would be a Helmert ...

      Guideline Normal orthometric heights should be determined for control marks whenever they are surveyed by or for LINZ. Heights should be determined using direct height measurements from adjacent marks with existing normal orthometric heights where the accuracy of the existing height is better than that which can be determined from (d).
