AI8085.The horizontal coordinates were established by GPS observations
AI8085.and adjusted by the National Geodetic Survey in October 2000.
AI8085
AI8085.The orthometric height was determined by GPS observations and a
AI8085.high-resolution geoid model.
AI8085
AI8085.The X, Y, and Z were computed from the position and the ellipsoidal ht.
AI8085
AI8085.The Laplace correction was computed from DEFLEC99 derived deflections.
AI8085
AI8085.The ellipsoidal height was determined by GPS observations
AI8085.and is referenced to NAD 83.
AI8085
AI8085.The geoid height was determined by GEOID99.
