PIT utilizes readily available computer software and hardware to visually document underwater cultural and biological resources. Photographs or video images are digitized and saved as a file in the computer. The resulting product is a simple representation of the actual site, with excellent resolution of selected features.
PIT enables site plans to be developed with minimal diving and computer time.
One of the famous 1733 Spanish vessels wrecked in the Florida Keys, and among the Florida Keys oldest artificial reefs, the San Pedro was established as Florida's second underwater shipwreck park on April 1, 1989. The site has numerous 19th century sailing vessel components, and maybe associated with the wreck of the 1887 Slobodna . Perhaps the most significant archaeological site in the Caribbean, the sinkhole Manantial de la Aleta is under investigation by Indiana University. The site contains rare intact artifacts from the Taino Indians who greeted Columbus upon his arrival in the New World. PIT has been applied to the resulting maps.
