surrounding the disc. The disc is in good shape.

Found this one while I was in town for a meeting today.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in February 2000.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
  • 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.
