 GQ0299.The horizontal coordinates were established by classical geodetic methods
 GQ0299.and adjusted by the National Geodetic Survey in August 1993.
 GQ0299.
 GQ0299.The orthometric height was scaled from a topographic map.
 GQ0299
 GQ0299.Significant digits in the geoid height do not necessarily reflect accuracy.
 GQ0299.GEOID12B height accuracy estimate available here.
