RD0446
RD0446.The horizontal coordinates were scaled from a topographic map and have
RD0446.an estimated accuracy of +/- 6 seconds.
RD0446
RD0446.The orthometric height was determined by differential leveling
RD0446.and adjusted by the National Geodetic Survey in June 1991.
RD0446.WARNING-Repeat measurements at this control monument indicate possible
RD0446.vertical movement.
RD0446
RD0446.The geoid height was determined by GEOID99.
RD0446
RD0446.The dynamic height is computed by dividing the NAVD 88
RD0446.geopotential number by the normal gravity value computed on the
RD0446.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
RD0446.degrees latitude (G = 980.6199 gals.).
RD0446
RD0446.The modeled gravity was interpolated from observed gravity values.
