 LT0612.The horizontal coordinates were established by classical geodetic methods
 LT0612.and adjusted by the National Geodetic Survey in March 1994.
 LT0612.The horizontal coordinates are valid at the epoch date displayed above.
 LT0612.The epoch date for horizontal control is a decimal equivalence
 LT0612.of Year/Month/Day.
 LT0612
 LT0612.The NAVD 88 height was computed by applying the VERTCON shift value to
 LT0612.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 LT0612
 LT0612.The Laplace correction was computed from DEFLEC99 derived deflections.
 LT0612
 LT0612.The geoid height was determined by GEOID99.
