MF0281.The horizontal coordinates were scaled from a topographic map and have
MF0281.an estimated accuracy of +/- 6 seconds.
MF0281
MF0281.The orthometric height was determined by differential leveling
MF0281.and adjusted by the National Geodetic Survey in June 1991.
MF0281
MF0281.The geoid height was determined by GEOID99.
MF0281
MF0281.The dynamic height is computed by dividing the NAVD 88
MF0281.geopotential number by the normal gravity value computed on the
MF0281.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MF0281.degrees latitude (g = 980.6199 gals.).
MF0281
MF0281.The modeled gravity was interpolated from observed gravity values.
