DJ0971 DJ0971.The orthometric height was determined by differential leveling DJ0971.and adjusted by the National Geodetic Survey in June 1991. DJ0971.WARNING-Repeat measurements at this control monument indicate possible DJ0971.vertical movement. DJ0971 DJ0971.The geoid height was determined by GEOID99. DJ0971 DJ0971.The dynamic height is computed by dividing the NAVD 88 DJ0971.geopotential number by the normal gravity value computed on the DJ0971.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 DJ0971.degrees latitude (g = 980.6199 gals.). DJ0971 DJ0971.The modeled gravity was interpolated from observed gravity values. DJ0971 DJ0971; North East Units Estimated Accuracy DJ0971;SPC MS E - 455,060. 317,270.
