MY2092
MY2092.The horizontal coordinates were scaled from a topographic map and have
MY2092.an estimated accuracy of +/- 6 seconds.
MY2092
MY2092.The orthometric height was determined by differential leveling
MY2092.and adjusted by the National Geodetic Survey in June 1991.
MY2092
MY2092.The geoid height was determined by GEOID99.
MY2092
MY2092.The dynamic height is computed by dividing the NAVD 88
MY2092.geopotential number by the normal gravity value computed on the
MY2092.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MY2092.degrees latitude (g = 980.6199 gals.).
MY2092
MY2092.The modeled gravity was interpolated from observed gravity values.
