LC0750
LC0750.The horizontal coordinates were scaled from a topographic map and have
LC0750.an estimated accuracy of +/- 6 seconds.
LC0750
LC0750.The orthometric height was determined by differential leveling
LC0750.and adjusted by the National Geodetic Survey in June 1991.
LC0750
LC0750.The geoid height was determined by GEOID99.
LC0750
LC0750.The dynamic height is computed by dividing the NAVD 88
LC0750.geopotential number by the normal gravity value computed on the
LC0750.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0750.degrees latitude (g = 980.6199 gals.).
LC0750
LC0750.The modeled gravity was interpolated from observed gravity values.
