CZ0342.The horizontal coordinates were established by GPS observations
CZ0342.and adjusted by the National Geodetic Survey in September 1992.
CZ0342
CZ0342.The orthometric height was determined by differential leveling
CZ0342.and adjusted by the National Geodetic Survey in June 1991.
CZ0342
CZ0342.The X, Y, and Z were computed from the position and the ellipsoidal ht.
CZ0342
CZ0342.The Laplace correction was computed from DEFLEC99 derived deflections.
CZ0342
CZ0342.The ellipsoidal height was determined by GPS observations
CZ0342.and is referenced to NAD 83.
CZ0342
CZ0342.The geoid height was determined by GEOID99.
CZ0342
CZ0342.The dynamic height is computed by dividing the NAVD 88
CZ0342.geopotential number by the normal gravity value computed on the
CZ0342.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
CZ0342.degrees latitude (G = 980.6199 gals.).
CZ0342
CZ0342.The modeled gravity was interpolated from observed gravity values.
