CZ0496
CZ0496.The horizontal coordinates were scaled from a topographic map and have
CZ0496.an estimated accuracy of +/- 6 seconds.
CZ0496
CZ0496.The orthometric height was determined by differential leveling
CZ0496.and adjusted by the National Geodetic Survey in June 1991.
CZ0496
CZ0496.The geoid height was determined by GEOID99.
CZ0496
CZ0496.The dynamic height is computed by dividing the NAVD 88
CZ0496.geopotential number by the normal gravity value computed on the
CZ0496.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
CZ0496.degrees latitude (G = 980.6199 gals.).
CZ0496
CZ0496.The modeled gravity was interpolated from observed gravity values.
