RD0690.The horizontal coordinates were scaled from a topographic map and have
RD0690.an estimated accuracy of +/- 6 seconds.
RD0690
RD0690.The orthometric height was determined by differential leveling
RD0690.and adjusted by the National Geodetic Survey in June 1991.
RD0690
RD0690.The geoid height was determined by GEOID99.
RD0690
RD0690.The dynamic height is computed by dividing the NAVD 88
RD0690.geopotential number by the normal gravity value computed on the
RD0690.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
RD0690.degrees latitude (G = 980.6199 gals.).
RD0690
RD0690.The modeled gravity was interpolated from observed gravity values.
