| Abstract | Coral reef is known as the most complex and diverse ecosystem. The Coral reefs in Thailand are important as attractive tourist place because of the variety of coral. Most of the coral reefs found in Thailand are Fringing Reef. The Phi Phi Island offers a good variety of different types of diving with abundant hard and soft corals and healthy fish populations. There has been a huge growth in the diving and hotel business. Integrated Coastal Zone Management (ICZM) has been proposed as a comprehensive, interdisciplinary and adaptive approach for addressing complex issues concerning the conservation and sustainable development of coastal resources. This research aimed at developing the approach of using fused image of high spatial resolution and multispectral, Panchromatic and LISS III sensor of IRS-lD, for making coral habitat map. The mixing habitat could be more distinguished through high resolution 5.8 m. Study of benthic features with higher precision, ground survey for training area is required and only a limited number of areas can be investigated. Therefore, it seems necessary to take advantage of the increasing number of sites surveyed by the monitoring organizations (ReefCheck, GCRMN etc.) for a fruitful exchange. This study adjusts the standard method of ReefCheck organization, which is used by volunteer around the world, for the purpose of remote sensing of coral reef. Water column correction is used to eliminate the influence of the depth before supervised classification using ten classes from multivariate classification of field survey for training area. The result of classification, is the habitat type image, is then identified in term of quality of coral reef. The rule for identification habitat zone map use the ratio of percentage cover of live coral and dead coral followed by the standard rule of Coral reef maps in Thai water made by Phuket Marine Biological Center (PMBC). In the study area, four zones of the reef habitat, except in "Good zone" and "Damaged zone'', are explored from the remote sensing data processing techniques and modeling. |
