TT2259
TT2259.The horizontal coordinates were scaled from a topographic map and have
TT2259.an estimated accuracy of +/- 6 seconds.
TT2259
TT2259.The orthometric height was determined by differential leveling
TT2259.and adjusted by the National Geodetic Survey in June 1991.
TT2259
TT2259.The geoid height was determined by GEOID99.
TT2259
TT2259.The dynamic height is computed by dividing the NAVD 88
TT2259.geopotential number by the normal gravity value computed on the
TT2259.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
TT2259.degrees latitude (G = 980.6199 gals.).
TT2259
TT2259.The modeled gravity was interpolated from observed gravity values.
