CZ2374.The horizontal coordinates were established by GPS observations
CZ2374.and adjusted by the National Geodetic Survey in August 1993.
CZ2374
CZ2374.The NAVD 88 height was computed by applying the VERTCON shift value to
CZ2374.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
CZ2374
CZ2374.The X, Y, and Z were computed from the position and the ellipsoidal ht.
CZ2374
CZ2374.The Laplace correction was computed from DEFLEC99 derived deflections.
CZ2374
CZ2374.The ellipsoidal height was determined by GPS observations
CZ2374.and is referenced to NAD 83.
CZ2374
CZ2374.The geoid height was determined by GEOID99.
