 HR2855.The horizontal coordinates were established by GPS observations
 HR2855.and adjusted by the National Geodetic Survey in July 1997.
 HR2855.The horizontal coordinates are valid at the epoch date displayed above.
 HR2855.The epoch date for horizontal control is a decimal equivalence
 HR2855.of Year/Month/Day.
 HR2855
 HR2855.The orthometric height was determined by GPS observations and a
 HR2855.high-resolution geoid model.
 HR2855
 HR2855.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HR2855
 HR2855.The Laplace correction was computed from DEFLEC99 derived deflections.
 HR2855
 HR2855.The ellipsoidal height was determined by GPS observations
 HR2855.and is referenced to NAD 83.
 HR2855
 HR2855.The geoid height was determined by GEOID03.
