 DX4930.The horizontal coordinates were established by classical geodetic methods
 DX4930.and adjusted by the National Geodetic Survey in June 1996.
 DX4930.The horizontal coordinates are valid at the epoch date displayed above.
 DX4930.The epoch date for horizontal control is a decimal equivalence
 DX4930.of Year/Month/Day.
 DX4930
 DX4930.The NAVD 88 height was computed by applying the VERTCON shift value to
 DX4930.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DX4930
 DX4930.The Laplace correction was computed from DEFLEC99 derived deflections.
 DX4930
 DX4930.The geoid height was determined by GEOID99.
