The physiographic zones of Wistari Reef

Wistari Reef is a lagoonal platform reef, situated on the Tropic of Capricorn, within the Capricorn and Bunker region of the southern Great Barrier Reef. Remote sensing data (Landsat TM image) and the application ER Mapper 5.5 was used to differentiate Wistari Reef into 5 zones: Surf zone / reef rim, Reef flats, Sanded Reef flats, Lagoon and Leeward Reef Edge. The area of each is determined with the lagoon physiographic zone exhibiting the greatest area, followed by the reef flats.
