AH9190
AH9190.The horizontal coordinates were scaled from a topographic map and have
AH9190.an estimated accuracy of +/- 6 seconds.
AH9190
AH9190.The orthometric height was determined by differential leveling
AH9190.and adjusted by the National Geodetic Survey in January 2001.
AH9190.No vertical observational check was made to the station.
AH9190
AH9190.The geoid height was determined by GEOID99.
AH9190
AH9190.The dynamic height is computed by dividing the NAVD 88
AH9190.geopotential number by the normal gravity value computed on the
AH9190.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
AH9190.degrees latitude (g = 980.6199 gals.).
AH9190
AH9190.The modeled gravity was interpolated from observed gravity values.
