 PB0701.The horizontal coordinates were established by classical geodetic methods
 PB0701.and adjusted by the National Geodetic Survey in October 1991.
 PB0701
 PB0701.The orthometric height was scaled from a topographic map.
 PB0701
 PB0701.The Laplace correction was computed from DEFLEC09 derived deflections.
 PB0701
 PB0701.The geoid height was determined by GEOID09.
