GP0266.The horizontal coordinates were scaled from a topographic map and have
GP0266.an estimated accuracy of +/- 6 seconds.
GP0266
GP0266.The orthometric height was determined by differential leveling
GP0266.and adjusted by the National Geodetic Survey in 1992.
GP0266.* This is a POSTED BENCH MARK height.  Code A indicates a distribution
GP0266.rate of 0.0 thru 1.0 mm/km.
GP0266
GP0266.The geoid height was determined by GEOID99.
GP0266
GP0266.The dynamic height is computed by dividing the NAVD 88
GP0266.geopotential number by the normal gravity value computed on the
GP0266.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
GP0266.degrees latitude (G = 980.6199 gals.).
GP0266
GP0266.The modeled gravity was interpolated from observed gravity values.
