DN0652.The horizontal coordinates were scaled from a topographic map and have
DN0652.an estimated accuracy of +/- 6 seconds.
DN0652
DN0652.The orthometric height was determined by differential leveling
DN0652.and adjusted by the National Geodetic Survey in June 1991.
DN0652
DN0652.The geoid height was determined by GEOID99.
DN0652
DN0652.The dynamic height is computed by dividing the NAVD 88
DN0652.geopotential number by the normal gravity value computed on the
DN0652.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DN0652.degrees latitude (G = 980.6199 gals.).
DN0652
DN0652.The modeled gravity was interpolated from observed gravity values.
