LY1338
LY1338.The horizontal coordinates were scaled from a topographic map and have
LY1338.an estimated accuracy of +/- 6 seconds.
LY1338
LY1338.The orthometric height was determined by differential leveling
LY1338.and adjusted by the National Geodetic Survey in June 1991.
LY1338.WARNING-Repeat measurements at this control monument indicate possible
LY1338.vertical movement.
LY1338
LY1338.The geoid height was determined by GEOID99.
LY1338
LY1338.The dynamic height is computed by dividing the NAVD 88
LY1338.geopotential number by the normal gravity value computed on the
LY1338.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
LY1338.degrees latitude (g = 980.6199 gals.).
LY1338
LY1338.The modeled gravity was interpolated from observed gravity values.
