MG0367.The horizontal coordinates were scaled from a topographic map and have
MG0367.an estimated accuracy of +/- 6 seconds.
MG0367
MG0367.The orthometric height was determined by differential leveling
MG0367.and adjusted by the National Geodetic Survey in June 1991.
MG0367.WARNING-Repeat measurements at this control monument indicate possible
MG0367.vertical movement.
MG0367
MG0367.The geoid height was determined by GEOID99.
MG0367
MG0367.The dynamic height is computed by dividing the NAVD 88
MG0367.geopotential number by the normal gravity value computed on the
MG0367.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MG0367.degrees latitude (g = 980.6199 gals.).
MG0367
MG0367.The modeled gravity was interpolated from observed gravity values.
