AB4331.The horizontal coordinates were established by GPS observations
AB4331.and adjusted by the National Geodetic Survey in September 1997.
AB4331
AB4331.The orthometric height was determined by GPS observations and a
AB4331.high-resolution geoid model.
AB4331
AB4331.The X, Y, and Z were computed from the position and the ellipsoidal ht.
AB4331
AB4331.The Laplace correction was computed from DEFLEC99 derived deflections.
AB4331
AB4331.The ellipsoidal height was determined by GPS observations
AB4331.and is referenced to NAD 83.
AB4331
AB4331.The geoid height was determined by GEOID99.
