TO0461.The horizontal coordinates were scaled from a topographic map and have
TO0461.an estimated accuracy of +/- 6 seconds.
TO0461
TO0461.The orthometric height was determined by differential leveling
TO0461.and adjusted by the National Geodetic Survey in June 1991.
TO0461
TO0461.The geoid height was determined by GEOID99.
TO0461
TO0461.The dynamic height is computed by dividing the NAVD 88
TO0461.geopotential number by the normal gravity value computed on the
TO0461.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
TO0461.degrees latitude (G = 980.6199 gals.).
TO0461
TO0461.The modeled gravity was interpolated from observed gravity values.
