AA4618.This mark is at Wittman Regional Airport (OSH)
AA4618
AA4618.The horizontal coordinates were established by GPS observations
AA4618.and adjusted by the National Geodetic Survey in May 1999.
AA4618.No horizontal observational check was made to the station.
AA4618
AA4618.The NAVD 88 height was computed by applying the VERTCON shift value to
AA4618.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
AA4618
AA4618.GPS derived orthometric heights for airport stations designated as
AA4618.PACS or SACS are published to 2 decimal places.  This maintains
AA4618.centimeter relative accuracy between the PACS and SACS.  It does
AA4618.not indicate centimeter accuracy relative to other marks which are
AA4618.part of the NAVD 88 network.
AA4618.The vertical order pertains to the superseded datum.
AA4618
AA4618.The X, Y, and Z were computed from the position and the ellipsoidal ht.
AA4618
AA4618.The Laplace correction was computed from DEFLEC99 derived deflections.
AA4618
AA4618.The ellipsoidal height was determined by GPS observations
AA4618.and is referenced to NAD 83.
AA4618
AA4618.The geoid height was determined by GEOID99.
