AB8609
AB8609.The horizontal coordinates were scaled from a topographic map and have
AB8609.an estimated accuracy of +/- 6 seconds.
AB8609
AB8609.The orthometric height was determined by differential leveling
AB8609.and adjusted by the National Geodetic Survey in February 1997.
AB8609
AB8609.The geoid height was determined by GEOID99.
AB8609
AB8609.The dynamic height is computed by dividing the NAVD 88
AB8609.geopotential number by the normal gravity value computed on the
AB8609.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
AB8609.degrees latitude (G = 980.6199 gals.).
AB8609
AB8609.The modeled gravity was interpolated from observed gravity values.
