RD0427.The horizontal coordinates were scaled from a topographic map and have
RD0427.an estimated accuracy of +/- 6 seconds.
RD0427
RD0427.The orthometric height was determined by differential leveling
RD0427.and adjusted by the National Geodetic Survey in 1992.
RD0427.No vertical observational check was made to the station.
RD0427.* This is a POSTED BENCH MARK height.  Code NC indicates the bench mark
RD0427.was located on a no-check spur therefore a value was not computed.
RD0427
RD0427.The geoid height was determined by GEOID99.
RD0427
RD0427.The dynamic height is computed by dividing the NAVD 88
RD0427.geopotential number by the normal gravity value computed on the
RD0427.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
RD0427.degrees latitude (G = 980.6199 gals.).
RD0427
RD0427.The modeled gravity was interpolated from observed gravity values.
