RY0100.The horizontal coordinates were scaled from a topographic map and have
RY0100.an estimated accuracy of +/- 6 seconds.
RY0100
RY0100.The orthometric height was determined by differential leveling
RY0100.and adjusted by the National Geodetic Survey in June 1991.
RY0100
RY0100.The geoid height was determined by GEOID99.
RY0100
RY0100.The dynamic height is computed by dividing the NAVD 88
RY0100.geopotential number by the normal gravity value computed on the
RY0100.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
RY0100.degrees latitude (g = 980.6199 gals.).
RY0100
RY0100.The modeled gravity was interpolated from observed gravity values.
