 DX4909.The horizontal coordinates were established by classical geodetic methods
 DX4909.and adjusted by the National Geodetic Survey in June 1996.
 DX4909.The horizontal coordinates are valid at the epoch date displayed above.
 DX4909.The epoch date for horizontal control is a decimal equivalence
 DX4909.of Year/Month/Day.
 DX4909
 DX4909.The NAVD 88 height was computed by applying the VERTCON shift value to
 DX4909.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DX4909
 DX4909.The Laplace correction was computed from DEFLEC99 derived deflections.
 DX4909
 DX4909.The geoid height was determined by GEOID03.
