HX2122.The horizontal coordinates were scaled from a topographic map and have
HX2122.an estimated accuracy of +/- 6 seconds.
HX2122
HX2122.The orthometric height was determined by differential leveling
HX2122.and adjusted by the National Geodetic Survey in June 1991.
HX2122
HX2122.The geoid height was determined by GEOID99.
HX2122
HX2122.The dynamic height is computed by dividing the NAVD 88
HX2122.geopotential number by the normal gravity value computed on the
HX2122.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
HX2122.degrees latitude (g = 980.6199 gals.).
HX2122
HX2122.The modeled gravity was interpolated from observed gravity values.
