AH8552.This mark is at Cherokee County Airport (47A)
AH8552
AH8552.The horizontal coordinates were established by GPS observations
AH8552.and adjusted by the National Geodetic Survey in September 1999.
AH8552
AH8552.The orthometric height was determined by GPS observations and a
AH8552.high-resolution geoid model.
AH8552
AH8552.GPS derived orthometric heights for airport stations designated as
AH8552.PACS or SACS are published to 2 decimal places.  This maintains
AH8552.centimeter relative accuracy between the PACS and SACS.  It does
AH8552.not indicate centimeter accuracy relative to other marks which are
AH8552.part of the NAVD 88 network.
AH8552
AH8552.The X, Y, and Z were computed from the position and the ellipsoidal ht.
AH8552
AH8552.The Laplace correction was computed from DEFLEC99 derived deflections.
AH8552
AH8552.The ellipsoidal height was determined by GPS observations
AH8552.and is referenced to NAD 83.
AH8552
AH8552.The geoid height was determined by GEOID99.
