JS3956.The horizontal coordinates are valid at the epoch date displayed above. JS3956.The epoch date for horizontal control is a decimal equivalence JS3956.of Year/Month/Day. JS3956 JS3956.The orthometric height was scaled from a topographic map. JS3956 JS3956.The Laplace correction was computed from DEFLEC99 derived deflections.
