LW0690.The horizontal coordinates were scaled from a topographic map and have
LW0690.an estimated accuracy of +/- 6 seconds.
LW0690
LW0690.The orthometric height was determined by differential leveling
LW0690.and adjusted by the National Geodetic Survey in June 1991.
LW0690
LW0690.The geoid height was determined by GEOID99.
LW0690
LW0690.The dynamic height is computed by dividing the NAVD 88
LW0690.geopotential number by the normal gravity value computed on the
LW0690.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LW0690.degrees latitude (g = 980.6199 gals.).
LW0690
LW0690.The modeled gravity was interpolated from observed gravity values.
