DU0459.The horizontal coordinates were scaled from a topographic map and have
DU0459.an estimated accuracy of +/- 6 seconds.
DU0459
DU0459.The orthometric height was determined by differential leveling
DU0459.and adjusted by the National Geodetic Survey in June 1991.
DU0459
DU0459.The geoid height was determined by GEOID99.
DU0459
DU0459.The dynamic height is computed by dividing the NAVD 88
DU0459.geopotential number by the normal gravity value computed on the
DU0459.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DU0459.degrees latitude (G = 980.6199 gals.).
DU0459
DU0459.The modeled gravity was interpolated from observed gravity values.
