NM0016.The horizontal coordinates were scaled from a topographic map and have
NM0016.an estimated accuracy of +/- 6 seconds.
NM0016
NM0016.The orthometric height was determined by differential leveling
NM0016.and adjusted by the National Geodetic Survey in June 1991.
NM0016
NM0016.The geoid height was determined by GEOID99.
NM0016
NM0016.The dynamic height is computed by dividing the NAVD 88
NM0016.geopotential number by the normal gravity value computed on the
NM0016.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
NM0016.degrees latitude (g = 980.6199 gals.).
NM0016
NM0016.The modeled gravity was interpolated from observed gravity values.
