LA0021.The horizontal coordinates were scaled from a topographic map and have
LA0021.an estimated accuracy of +/- 6 seconds.
LA0021
LA0021.The orthometric height was determined by differential leveling
LA0021.and adjusted by the National Geodetic Survey in June 1991.
LA0021
LA0021.The geoid height was determined by GEOID99.
LA0021
LA0021.The dynamic height is computed by dividing the NAVD 88
LA0021.geopotential number by the normal gravity value computed on the
LA0021.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LA0021.degrees latitude (g = 980.6199 gals.).
LA0021
LA0021.The modeled gravity was interpolated from observed gravity values.
