 EV3809.The horizontal coordinates were established by classical geodetic methods
 EV3809.and adjusted by the National Geodetic Survey in June 1996.
 EV3809.The horizontal coordinates are valid at the epoch date displayed above.
 EV3809.The epoch date for horizontal control is a decimal equivalence
 EV3809.of Year/Month/Day.
 EV3809
 EV3809.The NAVD 88 height was computed by applying the VERTCON shift value to
 EV3809.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 EV3809
 EV3809.The Laplace correction was computed from DEFLEC99 derived deflections.
 EV3809
 EV3809.The geoid height was determined by GEOID03.
