DU2258.The horizontal coordinates were established by GPS observations
DU2258.and adjusted by the National Geodetic Survey in August 1993.

DU2258.The NAVD 88 height was computed by applying the VERTCON shift value to
DU2258.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
DU2258
DU2258.The X, Y, and Z were computed from the position and the ellipsoidal ht.
DU2258
DU2258.The Laplace correction was computed from DEFLEC99 derived deflections.
DU2258
DU2258.The ellipsoidal height was determined by GPS observations
DU2258.and is referenced to NAD 83.
DU2258
DU2258.The geoid height was determined by GEOID99.
