MB1317.The horizontal coordinates were established by GPS observations<br />

MB1317.and adjusted by the National Geodetic Survey in August 1996.<br />

MB1317<br />

MB1317.The orthometric height was determined by differential leveling<br />

MB1317.and adjusted by the National Geodetic Survey in June 1991.<br />

MB1317<br />

MB1317.The X, Y, and Z were computed from the position and the ellipsoidal ht.<br />

MB1317<br />

MB1317.The Laplace correction was computed from DEFLEC99 derived deflections.<br />

MB1317<br />

MB1317.The ellipsoidal height was determined by GPS observations<br />

MB1317.and is referenced to NAD 83.<br />

MB1317<br />

MB1317.The geoid height was determined by GEOID03.<br />

MB1317<br />

MB1317.The dynamic height is computed by dividing the NAVD 88<br />

MB1317.geopotential number by the normal gravity value computed on the<br />

MB1317.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45<br />
