MF1257
MF1257.The horizontal coordinates were scaled from a topographic map and have
MF1257.an estimated accuracy of +/- 6 seconds.
MF1257
MF1257.The orthometric height was determined by differential leveling
MF1257.and adjusted by the National Geodetic Survey in June 1991.
MF1257
MF1257.The geoid height was determined by GEOID99.
MF1257
MF1257.The dynamic height is computed by dividing the NAVD 88
MF1257.geopotential number by the normal gravity value computed on the
MF1257.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MF1257.degrees latitude (g = 980.6199 gals.).
MF1257
MF1257.The modeled gravity was interpolated from observed gravity values.
