LF0490.The horizontal coordinates were scaled from a topographic map and have
LF0490.an estimated accuracy of +/- 6 seconds.
LF0490
LF0490.The orthometric height was determined by differential leveling
LF0490.and adjusted by the National Geodetic Survey in June 1991.
LF0490
LF0490.The geoid height was determined by GEOID99.
LF0490
LF0490.The dynamic height is computed by dividing the NAVD 88
LF0490.geopotential number by the normal gravity value computed on the
LF0490.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LF0490.degrees latitude (g = 980.6199 gals.).
LF0490
LF0490.The modeled gravity was interpolated from observed gravity values.
