 NW0401.The horizontal coordinates were established by classical geodetic methods
 NW0401.and adjusted by the National Geodetic Survey in July 1992.
 NW0401.
 NW0401.The NAVD 88 height was computed by applying the VERTCON shift value to
 NW0401.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
