 DW0877.The horizontal coordinates were established by classical geodetic methods
 DW0877.and adjusted by the National Geodetic Survey in August 1993.
 DW0877
 DW0877.The NAVD 88 height was computed by applying the VERTCON shift value to
 DW0877.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DW0877
 DW0877.The Laplace correction was computed from DEFLEC99 derived deflections.
 DW0877
 DW0877.The geoid height was determined by GEOID99.
