GA0580.The horizontal coordinates were scaled from a topographic map and have
GA0580.an estimated accuracy of +/- 6 seconds.
GA0580
GA0580.The orthometric height was determined by differential leveling
GA0580.and adjusted by the National Geodetic Survey in June 1991.
GA0580
GA0580.The geoid height was determined by GEOID99.
GA0580
GA0580.The dynamic height is computed by dividing the NAVD 88
GA0580.geopotential number by the normal gravity value computed on the
GA0580.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
GA0580.degrees latitude (g = 980.6199 gals.).
GA0580
GA0580.The modeled gravity was interpolated from observed gravity values.
