OQ0047
OQ0047.The horizontal coordinates were scaled from a topographic map and have
OQ0047.an estimated accuracy of +/- 6 seconds.
OQ0047
OQ0047.The orthometric height was determined by differential leveling
OQ0047.and adjusted by the National Geodetic Survey in September 1993.
OQ0047
OQ0047.The geoid height was determined by GEOID99.
OQ0047
OQ0047.The dynamic height is computed by dividing the NAVD 88
OQ0047.geopotential number by the normal gravity value computed on the
OQ0047.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
OQ0047.degrees latitude (g = 980.6199 gals.).
OQ0047
OQ0047.The modeled gravity was interpolated from observed gravity values.
