BM0435
BM0435.The horizontal coordinates were scaled from a topographic map and have
BM0435.an estimated accuracy of +/- 6 seconds.
BM0435
BM0435.The orthometric height was determined by differential leveling
BM0435.and adjusted by the National Geodetic Survey in June 1991.
BM0435
BM0435.The geoid height was determined by GEOID99.
BM0435
BM0435.The dynamic height is computed by dividing the NAVD 88
BM0435.geopotential number by the normal gravity value computed on the
BM0435.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
BM0435.degrees latitude (G = 980.6199 gals.).
BM0435
BM0435.The modeled gravity was interpolated from observed gravity values.
