OH0820.The horizontal coordinates were scaled from a topographic map and have
OH0820.an estimated accuracy of +/- 6 seconds.
OH0820
OH0820.The orthometric height was determined by differential leveling
OH0820.and adjusted by the National Geodetic Survey in 1992.
OH0820.* This is a POSTED BENCH MARK height.  Code A indicates a distribution
OH0820.rate of 0.0 thru 1.0 mm/km.
OH0820
OH0820.The geoid height was determined by GEOID99.
OH0820
OH0820.The dynamic height is computed by dividing the NAVD 88
OH0820.geopotential number by the normal gravity value computed on the
OH0820.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
OH0820.degrees latitude (G = 980.6199 gals.).
OH0820
OH0820.The modeled gravity was interpolated from observed gravity values.
