RD0397.The horizontal coordinates were scaled from a topographic map and have
RD0397.an estimated accuracy of +/- 6 seconds.
RD0397
RD0397.The orthometric height was determined by differential leveling
RD0397.and adjusted by the National Geodetic Survey in June 1991.
RD0397
RD0397.The geoid height was determined by GEOID99.
RD0397
RD0397.The dynamic height is computed by dividing the NAVD 88
RD0397.geopotential number by the normal gravity value computed on the
RD0397.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
RD0397.degrees latitude (G = 980.6199 gals.).
RD0397
RD0397.The modeled gravity was interpolated from observed gravity values.
