LC0723.The horizontal coordinates were scaled from a topographic map and have
LC0723.an estimated accuracy of +/- 6 seconds.
LC0723
LC0723.The orthometric height was determined by differential leveling
LC0723.and adjusted by the National Geodetic Survey in June 1991.
LC0723
LC0723.The geoid height was determined by GEOID99.
LC0723
LC0723.The dynamic height is computed by dividing the NAVD 88
LC0723.geopotential number by the normal gravity value computed on the
LC0723.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0723.degrees latitude (g = 980.6199 gals.).
LC0723
LC0723.The modeled gravity was interpolated from observed gravity values.
