LV0361.The horizontal coordinates were scaled from a topographic map and have
LV0361.an estimated accuracy of +/- 6 seconds.
LV0361.
LV0361.The orthometric height was determined by differential leveling and
LV0361.adjusted by the NATIONAL GEODETIC SURVEY
LV0361.in June 1991.
LV0361
LV0361.Significant digits in the geoid height do not necessarily reflect accuracy.
LV0361.GEOID12B height accuracy estimate available here.

LV0361.This Tidal Bench Mark is designated as VM 1717
LV0361.by the CENTER FOR OPERATIONAL OCEANOGRAPHIC PRODUCTS AND SERVICES.
LV0361
LV0361.The dynamic height is computed by dividing the NAVD 88
LV0361.geopotential number by the normal gravity value computed on the
LV0361.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LV0361.degrees latitude (g = 980.6199 gals.).
LV0361
LV0361.The modeled gravity was interpolated from observed gravity values.
