FS0168.The horizontal coordinates were scaled from a topographic map and have
FS0168.an estimated accuracy of +/- 6 seconds.
FS0168
FS0168.The orthometric height was determined by differential leveling
FS0168.and adjusted by the National Geodetic Survey in 1992.
FS0168.* This is a POSTED BENCH MARK height.  Code B indicates a distribution
FS0168.rate of 1.1 thru 2.0 mm/km.
FS0168
FS0168.The geoid height was determined by GEOID99.
FS0168
FS0168.The dynamic height is computed by dividing the NAVD 88
FS0168.geopotential number by the normal gravity value computed on the
FS0168.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
FS0168.degrees latitude (G = 980.6199 gals.).
FS0168
FS0168.The modeled gravity was interpolated from observed gravity values.
