DC0893
DC0893.The horizontal coordinates were scaled from a topographic map and have
DC0893.an estimated accuracy of +/- 6 seconds.
DC0893
DC0893.The orthometric height was determined by differential leveling
DC0893.and adjusted by the National Geodetic Survey in June 1991.
DC0893
DC0893.The geoid height was determined by GEOID99.
DC0893
DC0893.The dynamic height is computed by dividing the NAVD 88
DC0893.geopotential number by the normal gravity value computed on the
DC0893.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DC0893.degrees latitude (G = 980.6199 gals.).
DC0893
DC0893.The modeled gravity was interpolated from observed gravity values.
