LV0346. LV0346.The orthometric height was determined by differential leveling and LV0346.adjusted in June 1991. LV0346 LV0346.This Tidal Bench Mark is designated as VM 8747 LV0346.by the CENTER FOR OPERATIONAL OCEANOGRAPHIC PRODUCTS AND SERVICES. LV0346 LV0346.The geoid height was determined by GEOID09. LV0346 LV0346.The dynamic height is computed by dividing the NAVD 88 LV0346.geopotential number by the normal gravity value computed on the LV0346.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 LV0346.degrees latitude (g = 980.6199 gals.). LV0346 LV0346.The modeled gravity was interpolated from observed gravity values. LV0346 LV0346; North East Units Estimated Accuracy LV0346;SPC CA 1 - 672,300. 1,818,780.
