LC0692.The horizontal coordinates were scaled from a topographic map and have
LC0692.an estimated accuracy of +/- 6 seconds.
LC0692
LC0692.The orthometric height was determined by differential leveling
LC0692.and adjusted by the National Geodetic Survey in June 1991.
LC0692
LC0692.The geoid height was determined by GEOID99.
LC0692
LC0692.The dynamic height is computed by dividing the NAVD 88
LC0692.geopotential number by the normal gravity value computed on the
LC0692.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0692.degrees latitude (g = 980.6199 gals.).
LC0692
LC0692.The modeled gravity was interpolated from observed gravity values.
