Some forty species of scleractinian corals live in a particular, very muddy, environmment situated in the South-Western lagoon of New Caledonia between 25 and 30 metres depth. The seabed is caracterised by the topography of ridges valleys and bumps a...

Spot images for coral reef mapping in New Caledonia : a fruitful approach for classic and new topics;Proceedings of the sixth international coral reef...

... The following step described in this paper is the processing of real SPOT images for the same scope but extended to great areas of New Caledonian lagoon. LATICAL, a multi-purpose remote sensing laboratory, was set up in March 1988 at ORSTOM Cente...
