AA0918
AA0918.The horizontal coordinates were scaled from a topographic map and have
AA0918.an estimated accuracy of +/- 6 seconds.
AA0918
AA0918.The orthometric height was determined by differential leveling
AA0918.and adjusted by the National Geodetic Survey in June 1991.
AA0918
AA0918.This Tidal Bench Mark is designated as VM 9623
AA0918.by the Center for Operational Oceanographic Products and Services.
AA0918
AA0918.The geoid height was determined by GEOID99.
AA0918
AA0918.The dynamic height is computed by dividing the NAVD 88
AA0918.geopotential number by the normal gravity value computed on the
AA0918.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
AA0918.degrees latitude (g = 980.6199 gals.).
AA0918
AA0918.The modeled gravity was interpolated from observed gravity values.
