ME1433.The horizontal coordinates were scaled from a topographic map and have
ME1433.an estimated accuracy of +/- 6 seconds.
ME1433
ME1433.The orthometric height was determined by differential leveling
ME1433.and adjusted by the National Geodetic Survey in June 1991.
ME1433
ME1433.The geoid height was determined by GEOID99.
ME1433
ME1433.The dynamic height is computed by dividing the NAVD 88
ME1433.geopotential number by the normal gravity value computed on the
ME1433.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
ME1433.degrees latitude (g = 980.6199 gals.).
ME1433
ME1433.The modeled gravity was interpolated from observed gravity values.
