JZ0553
JZ0553.The horizontal coordinates were scaled from a topographic map and have
JZ0553.an estimated accuracy of +/- 6 seconds.
JZ0553
JZ0553.The orthometric height was determined by differential leveling
JZ0553.and adjusted by the National Geodetic Survey in June 1991.
JZ0553
JZ0553.The geoid height was determined by GEOID99.
JZ0553
JZ0553.The dynamic height is computed by dividing the NAVD 88
JZ0553.geopotential number by the normal gravity value computed on the
JZ0553.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
JZ0553.degrees latitude (g = 980.6199 gals.).
JZ0553
JZ0553.The modeled gravity was interpolated from observed gravity values.
