SC1127.The horizontal coordinates were established by classical geodetic methods
SC1127.and adjusted by the National Geodetic Survey in December 1991.
SC1127.No horizontal observational check was made to the station.
SC1127
SC1127.The orthometric height was determined by differential leveling
SC1127.and adjusted by the National Geodetic Survey in May 2000.
SC1127
SC1127.The X, Y, and Z were computed from the position and the ellipsoidal ht.
SC1127
SC1127.The Laplace correction was computed from DEFLEC99 derived deflections.
SC1127
SC1127.The ellipsoidal height was determined by GPS observations
SC1127.and is referenced to NAD 83.
SC1127
SC1127.The geoid height was determined by GEOID99.
SC1127
SC1127.The dynamic height is computed by dividing the NAVD 88
SC1127.geopotential number by the normal gravity value computed on the
SC1127.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
SC1127.degrees latitude (G = 980.6199 gals.).
SC1127
SC1127.The modeled gravity was interpolated from observed gravity values.
