DC0904
DC0904.The horizontal coordinates were scaled from a topographic map and have
DC0904.an estimated accuracy of +/- 6 seconds.
DC0904
DC0904.The orthometric height was determined by differential leveling
DC0904.and adjusted by the National Geodetic Survey in June 1991.
DC0904
DC0904.The geoid height was determined by GEOID99.
DC0904
DC0904.The dynamic height is computed by dividing the NAVD 88
DC0904.geopotential number by the normal gravity value computed on the
DC0904.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DC0904.degrees latitude (G = 980.6199 gals.).
DC0904
DC0904.The modeled gravity was interpolated from observed gravity values.
