 AB5120  VERT ORDER  -  SECOND    CLASS I
 AB5120
 AB5120.The horizontal coordinates were scaled from a topographic map and have
 AB5120.an estimated accuracy of +/- 6 seconds.
 AB5120
 AB5120.The orthometric height was determined by differential leveling
 AB5120.and adjusted by the National Geodetic Survey in September 1996.
 AB5120
 AB5120.The geoid height was determined by GEOID99.
 AB5120
 AB5120.The dynamic height is computed by dividing the NAVD 88
 AB5120.geopotential number by the normal gravity value computed on the
 AB5120.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AB5120.degrees latitude (g = 980.6199 gals.).
 AB5120
 AB5120.The modeled gravity was interpolated from observed gravity values.
