MD0321.The horizontal coordinates were scaled from a topographic map and have
MD0321.an estimated accuracy of +/- 6 seconds.
MD0321
MD0321.The orthometric height was determined by differential leveling
MD0321.and adjusted by the National Geodetic Survey in June 1991.
MD0321
MD0321.The geoid height was determined by GEOID99.
MD0321
MD0321.The dynamic height is computed by dividing the NAVD 88
MD0321.geopotential number by the normal gravity value computed on the
MD0321.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MD0321.degrees latitude (g = 980.6199 gals.).
MD0321
MD0321.The modeled gravity was interpolated from observed gravity values.
