CM0947
CM0947.The horizontal coordinates were scaled from a topographic map and have
CM0947.an estimated accuracy of +/- 6 seconds.
CM0947
CM0947.The orthometric height was determined by differential leveling
CM0947.and adjusted by the National Geodetic Survey in June 1991.
CM0947.WARNING-Repeat measurements at this control monument indicate possible
CM0947.vertical movement.
CM0947
CM0947.The geoid height was determined by GEOID99.
CM0947
CM0947.The dynamic height is computed by dividing the NAVD 88
CM0947.geopotential number by the normal gravity value computed on the
CM0947.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
CM0947.degrees latitude (g = 980.6199 gals.).
CM0947
CM0947.The modeled gravity was interpolated from observed gravity values.
