Photographic Imaging Technique (PIT)

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. Computer images are scaled, rotated, and placed into a "composite file" of the site being documented. 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.
