EF1011.The horizontal coordinates were scaled from a topographic map and have
EF1011.an estimated accuracy of +/- 6 seconds.
EF1011
EF1011.The orthometric height was determined by differential leveling
EF1011.and adjusted by the National Geodetic Survey in 1992.
EF1011.* This is a POSTED BENCH MARK height.  Code A indicates a distribution
EF1011.rate of 0.0 thru 1.0 mm/km.
EF1011
EF1011.The geoid height was determined by GEOID99.
EF1011
EF1011.The dynamic height is computed by dividing the NAVD 88
EF1011.geopotential number by the normal gravity value computed on the
EF1011.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
EF1011.degrees latitude (g = 980.6199 gals.).
EF1011
EF1011.The modeled gravity was interpolated from observed gravity values.
