 GW2230.The horizontal coordinates were established by classical geodetic methods
 GW2230.and adjusted by the National Geodetic Survey in September 1995.
 GW2230
 GW2230.The orthometric height was scaled from a topographic map.
 GW2230
 GW2230.The Laplace correction was computed from DEFLEC99 derived deflections.
 GW2230
 GW2230.The geoid height was determined by GEOID99.
