HC0228
HC0228.The horizontal coordinates were scaled from a topographic map and have
HC0228.an estimated accuracy of +/- 6 seconds.
HC0228
HC0228.The orthometric height was determined by differential leveling
HC0228.and adjusted by the National Geodetic Survey in June 1991.
HC0228
HC0228.The geoid height was determined by GEOID99.
HC0228
HC0228.The dynamic height is computed by dividing the NAVD 88
HC0228.geopotential number by the normal gravity value computed on the
HC0228.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
HC0228.degrees latitude (g = 980.6199 gals.).
HC0228
HC0228.The modeled gravity was interpolated from observed gravity values.
