 LV0634.The horizontal coordinates were scaled from a topographic map and have
 LV0634.an estimated accuracy of +/- 6 seconds.
 LV0634.
 LV0634.The orthometric height was determined by differential leveling and
 LV0634.adjusted in June 1991.
 LV0634
 LV0634.This Tidal Bench Mark is designated as VM 1720
 LV0634.by the CENTER FOR OPERATIONAL OCEANOGRAPHIC PRODUCTS AND SERVICES.
 LV0634
 LV0634.The geoid height was determined by GEOID09.
 LV0634
 LV0634.The dynamic height is computed by dividing the NAVD 88
 LV0634.geopotential number by the normal gravity value computed on the
 LV0634.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 LV0634.degrees latitude (g = 980.6199 gals.).
 LV0634
 LV0634.The modeled gravity was interpolated from observed gravity values.
