LL0218
LL0218.The horizontal coordinates were scaled from a topographic map and have
LL0218.an estimated accuracy of +/- 6 seconds.
LL0218
LL0218.The orthometric height was determined by differential leveling
LL0218.and adjusted by the National Geodetic Survey in June 1991.
LL0218
LL0218.The geoid height was determined by GEOID99.
LL0218
LL0218.The dynamic height is computed by dividing the NAVD 88
LL0218.geopotential number by the normal gravity value computed on the
LL0218.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LL0218.degrees latitude (G = 980.6199 gals.).
LL0218
LL0218.The modeled gravity was interpolated from observed gravity values.
