MB0358.The horizontal coordinates were scaled from a topographic map and have
MB0358.an estimated accuracy of +/- 6 seconds.
MB0358
MB0358.The orthometric height was determined by differential leveling
MB0358.and adjusted by the National Geodetic Survey in June 1991.
MB0358
MB0358.The geoid height was determined by GEOID99.
MB0358
MB0358.The dynamic height is computed by dividing the NAVD 88
MB0358.geopotential number by the normal gravity value computed on the
MB0358.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MB0358.degrees latitude (g = 980.6199 gals.).
MB0358
MB0358.The modeled gravity was interpolated from observed gravity values.
