DG0597.The horizontal coordinates were established by classical geodetic methods
DG0597.and adjusted by the National Geodetic Survey in September 1997.
DG0597
DG0597.The orthometric height was determined by differential leveling
DG0597.and adjusted by the National Geodetic Survey in June 1991.
DG0597
DG0597.The Laplace correction was computed from DEFLEC99 derived deflections.
DG0597
DG0597.The geoid height was determined by GEOID99.
DG0597
DG0597.The dynamic height is computed by dividing the NAVD 88
DG0597.geopotential number by the normal gravity value computed on the
DG0597.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DG0597.degrees latitude (g = 980.6199 gals.).
DG0597
DG0597.The modeled gravity was interpolated from observed gravity values.
