 LS0681.The horizontal coordinates were established by classical geodetic methods
 LS0681.and adjusted by the National Geodetic Survey in June 1998.
 LS0681
 LS0681.The NAVD 88 height was computed by applying the VERTCON shift value to
 LS0681.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 LS0681
 LS0681.The Laplace correction was computed from DEFLEC99 derived deflections.
 LS0681
 LS0681.The geoid height was determined by GEOID03.
