FC1291.The horizontal coordinates were scaled from a topographic map and have
FC1291.an estimated accuracy of +/- 6 seconds.
FC1291
FC1291.The orthometric height was determined by differential leveling
FC1291.and adjusted by the National Geodetic Survey in June 1991.
FC1291
FC1291.The geoid height was determined by GEOID99.
FC1291
FC1291.The dynamic height is computed by dividing the NAVD 88
FC1291.geopotential number by the normal gravity value computed on the
FC1291.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
FC1291.degrees latitude (g = 980.6199 gals.).
FC1291
FC1291.The modeled gravity was interpolated from observed gravity values.
