LC0668  VERT ORDER  -  FIRST     CLASS I
LC0668
LC0668.The horizontal coordinates were scaled from a topographic map and have
LC0668.an estimated accuracy of +/- 6 seconds.
LC0668
LC0668.The orthometric height was determined by differential leveling
LC0668.and adjusted by the National Geodetic Survey in June 1991.
LC0668
LC0668.The geoid height was determined by GEOID99.
LC0668
LC0668.The dynamic height is computed by dividing the NAVD 88
LC0668.geopotential number by the normal gravity value computed on the
LC0668.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0668.degrees latitude (g = 980.6199 gals.).
LC0668
LC0668.The modeled gravity was interpolated from observed gravity values.
