DC1719.The horizontal coordinates were established by classical geodetic methods
DC1719.and adjusted by the National Geodetic Survey in June 1996.
DC1719.The horizontal coordinates are valid at the epoch date displayed above.
DC1719.The epoch date for horizontal control is a decimal equivalence
DC1719.of Year/Month/Day.
DC1719
DC1719.The orthometric height was scaled from a topographic map.
DC1719
DC1719.The Laplace correction was computed from DEFLEC99 derived deflections.
DC1719
DC1719.The geoid height was determined by GEOID99.
