EU0769
EU0769.The horizontal coordinates were scaled from a topographic map and have
EU0769.an estimated accuracy of +/- 6 seconds.
EU0769
EU0769.The orthometric height was determined by differential leveling
EU0769.and adjusted by the National Geodetic Survey in June 1991.
EU0769
EU0769.The geoid height was determined by GEOID99.
EU0769
EU0769.The dynamic height is computed by dividing the NAVD 88
EU0769.geopotential number by the normal gravity value computed on the
EU0769.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
EU0769.degrees latitude (G = 980.6199 gals.).
EU0769
EU0769.The modeled gravity was interpolated from observed gravity values.
