LC0718.The horizontal coordinates were established by classical geodetic methods
LC0718.and adjusted by the National Geodetic Survey in October 1999.

LC0718.The orthometric height was determined by differential leveling
LC0718.and adjusted by the National Geodetic Survey in June 1991.
LC0718
LC0718.The Laplace correction was computed from DEFLEC99 derived deflections.
LC0718
LC0718.The geoid height was determined by GEOID99.
LC0718
LC0718.The dynamic height is computed by dividing the NAVD 88
LC0718.geopotential number by the normal gravity value computed on the
LC0718.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LC0718.degrees latitude (g = 980.6199 gals.).
LC0718
LC0718.The modeled gravity was interpolated from observed gravity values.
