PH1638.The horizontal coordinates were established by classical geodetic methods
PH1638.and adjusted by the National Geodetic Survey in January 1999.
PH1638
PH1638.The NAVD 88 height was computed by applying the VERTCON shift value to
PH1638.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
PH1638.The vertical order pertains to the superseded datum.
PH1638
PH1638.The Laplace correction was computed from DEFLEC99 derived deflections.
PH1638
PH1638.The geoid height was determined by GEOID99.
