LC1059.The horizontal coordinates were scaled from a topographic map and have
LC1059.an estimated accuracy of +/- 6 seconds.
LC1059
LC1059.The orthometric height was determined by differential leveling
LC1059.and adjusted by the National Geodetic Survey in June 1991.
LC1059
LC1059.The geoid height was determined by GEOID99.
LC1059
LC1059.The dynamic height is computed by dividing the NAVD 88
LC1059.geopotential number by the normal gravity value computed on the
LC1059.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC1059.degrees latitude (g = 980.6199 gals.).
LC1059
LC1059.The modeled gravity was interpolated from observed gravity values.
