Cool!

Not sure how long this monument will hold since somebody reditched some and the monument sits on its own mound of sand which is sure to wash away when the next hurricane comes through.

The Williams "Seafood" Restaurant was a victim of arson, but the benchmark remains (as seen in the photo). I had to uncover a bit to see, but what's a little dirt between control freaks.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1997.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.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 Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
