LC0693
LC0693.The horizontal coordinates were scaled from a topographic map and have
LC0693.an estimated accuracy of +/- 6 seconds.
LC0693
LC0693.The orthometric height was determined by differential leveling
LC0693.and adjusted by the National Geodetic Survey in June 1991.
LC0693
LC0693.The geoid height was determined by GEOID99.
LC0693
LC0693.The dynamic height is computed by dividing the NAVD 88
LC0693.geopotential number by the normal gravity value computed on the
LC0693.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0693.degrees latitude (g = 980.6199 gals.).
LC0693
LC0693.The modeled gravity was interpolated from observed gravity values.
