 JS4006.The horizontal coordinates were established by classical geodetic methods
 JS4006.and adjusted by the National Geodetic Survey in March 1994.
 JS4006.The horizontal coordinates are valid at the epoch date displayed above.
 JS4006.The epoch date for horizontal control is a decimal equivalence
 JS4006.of Year/Month/Day.
 JS4006
 JS4006.The orthometric height was scaled from a topographic map.
 JS4006
 JS4006.The Laplace correction was computed from DEFLEC99 derived deflections.
 JS4006
 JS4006.The geoid height was determined by GEOID03.
