Control Text

  • This mark is at Carroll Co-Tolson Airport (TSO)
  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in August 1996.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • GPS derived orthometric heights for airport stations designated as PACS or SACS are published to 2 decimal places. This maintains centimeter relative accuracy between the PACS and SACS. It does not indicate centimeter accuracy relative to other marks which are part of the NAVD 88 network.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • The geoid height was determined by GEOID99.
