NJ0583.The horizontal coordinates were scaled from a topographic map and have
NJ0583.an estimated accuracy of +/- 6 seconds.
NJ0583
NJ0583.The orthometric height was determined by differential leveling
NJ0583.and adjusted by the National Geodetic Survey in June 1991.
NJ0583
NJ0583.The geoid height was determined by GEOID99.
NJ0583
NJ0583.The dynamic height is computed by dividing the NAVD 88
NJ0583.geopotential number by the normal gravity value computed on the
NJ0583.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
NJ0583.degrees latitude (g = 980.6199 gals.).
NJ0583
NJ0583.The modeled gravity was interpolated from observed gravity values.
