 DX4950.The horizontal coordinates were established by classical geodetic methods
 DX4950.and adjusted by the National Geodetic Survey in June 1996.
 DX4950.
 DX4950.The NAVD 88 height was computed by applying the VERTCON shift value to
 DX4950.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DX4950
 DX4950.The Laplace correction was computed from DEFLEC12A derived deflections.
