JW0610.The horizontal coordinates were scaled from a topographic map and have
JW0610.an estimated accuracy of +/- 6 seconds.
JW0610
JW0610.The orthometric height was determined by differential leveling
JW0610.and adjusted by the National Geodetic Survey in June 1991.
JW0610
JW0610.The geoid height was determined by GEOID99.
JW0610
JW0610.The dynamic height is computed by dividing the NAVD 88
JW0610.geopotential number by the normal gravity value computed on the
JW0610.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
JW0610.degrees latitude (g = 980.6199 gals.).
JW0610
JW0610.The modeled gravity was interpolated from observed gravity values.
