LY2731.The horizontal coordinates were established by classical geodetic methods
LY2731.and adjusted by the National Geodetic Survey in September 1999.
LY2731
LY2731.The NAVD 88 height was computed by applying the VERTCON shift value to
LY2731.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
LY2731
LY2731.The Laplace correction was computed from DEFLEC99 derived deflections.
