 TN0949.The horizontal coordinates were established by classical geodetic methods
 TN0949.and adjusted by the National Geodetic Survey in July 1992.
 TN0949.
 TN0949.The NAVD 88 height was computed by applying the VERTCON shift value to
 TN0949.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
