LC0754.The horizontal coordinates were scaled from a topographic map and have
LC0754.an estimated accuracy of +/- 6 seconds.
LC0754
LC0754.The orthometric height was determined by differential leveling
LC0754.and adjusted by the National Geodetic Survey in June 1991.
LC0754
LC0754.The geoid height was determined by GEOID99.
LC0754
LC0754.The dynamic height is computed by dividing the NAVD 88
LC0754.geopotential number by the normal gravity value computed on the
LC0754.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0754.degrees latitude (g = 980.6199 gals.).
LC0754
LC0754.The modeled gravity was interpolated from observed gravity values.
