EW3439
EW3439.The horizontal coordinates were scaled from a topographic map and have
EW3439.an estimated accuracy of +/- 6 seconds.
EW3439
EW3439.The orthometric height was determined by differential leveling
EW3439.and adjusted by the National Geodetic Survey in June 1991.
EW3439.WARNING-Repeat measurements at this control monument indicate possible
EW3439.vertical movement.
EW3439
EW3439.The geoid height was determined by GEOID99.
EW3439
EW3439.The dynamic height is computed by dividing the NAVD 88
EW3439.geopotential number by the normal gravity value computed on the
EW3439.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
EW3439.degrees latitude (G = 980.6199 gals.).
EW3439
EW3439.The modeled gravity was interpolated from observed gravity values.
