AB8606
AB8606.The horizontal coordinates were scaled from a topographic map and have
AB8606.an estimated accuracy of +/- 6 seconds.
AB8606
AB8606.The orthometric height was determined by differential leveling
AB8606.and adjusted by the National Geodetic Survey in February 1997.
AB8606
AB8606.The geoid height was determined by GEOID99.
AB8606
AB8606.The dynamic height is computed by dividing the NAVD 88
AB8606.geopotential number by the normal gravity value computed on the
AB8606.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
AB8606.degrees latitude (G = 980.6199 gals.).
AB8606
AB8606.The modeled gravity was interpolated from observed gravity values.
