DN0771
DN0771.The horizontal coordinates were scaled from a topographic map and have
DN0771.an estimated accuracy of +/- 6 seconds.
DN0771
DN0771.The orthometric height was determined by differential leveling
DN0771.and adjusted by the National Geodetic Survey in June 1991.
DN0771
DN0771.The geoid height was determined by GEOID99.
DN0771
DN0771.The dynamic height is computed by dividing the NAVD 88
DN0771.geopotential number by the normal gravity value computed on the
DN0771.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DN0771.degrees latitude (G = 980.6199 gals.).
DN0771
DN0771.The modeled gravity was interpolated from observed gravity values.
