GF0470.The horizontal coordinates were scaled from a topographic map and have
GF0470.an estimated accuracy of +/- 6 seconds.
GF0470
GF0470.The orthometric height was determined by differential leveling
GF0470.and adjusted by the National Geodetic Survey in June 1991.
GF0470
GF0470.The geoid height was determined by GEOID99.
GF0470
GF0470.The dynamic height is computed by dividing the NAVD 88
GF0470.geopotential number by the normal gravity value computed on the
GF0470.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
GF0470.degrees latitude (G = 980.6199 gals.).
GF0470
GF0470.The modeled gravity was interpolated from observed gravity values.
