TP0004.The horizontal coordinates were scaled from a topographic map and have
TP0004.an estimated accuracy of +/- 6 seconds.
TP0004
TP0004.The orthometric height was determined by differential leveling
TP0004.and adjusted by the National Geodetic Survey in June 1991.
TP0004
TP0004.The geoid height was determined by GEOID99.
TP0004
TP0004.The dynamic height is computed by dividing the NAVD 88
TP0004.geopotential number by the normal gravity value computed on the
TP0004.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
TP0004.degrees latitude (G = 980.6199 gals.).
TP0004
TP0004.The modeled gravity was interpolated from observed gravity values.
