The document summarizes the structural and thematic mapping of the Tetembia Reef in New Caledonia using high resolution SPOT data. It identified several substrate types including soft bottom themes, coral debris, and living corals. Living branching corals and tubinaria corals over 2 meters were found along the outer reef slope and reticulate lagoonal reef. A sand/coral interface transition zone between soft bottom and living branching coral was also detected. The mapping revealed variations in coral densities and distributions influenced by cyclones.
