NE0629.The horizontal coordinates were scaled from a topographic map and have
NE0629.an estimated accuracy of +/- 6 seconds.
NE0629
NE0629.The orthometric height was determined by differential leveling
NE0629.and adjusted by the National Geodetic Survey in June 1991.
NE0629
NE0629.The geoid height was determined by GEOID99.
NE0629
NE0629.The dynamic height is computed by dividing the NAVD 88
NE0629.geopotential number by the normal gravity value computed on the
NE0629.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
NE0629.degrees latitude (g = 980.6199 gals.).
NE0629
NE0629.The modeled gravity was interpolated from observed gravity values.
