Abstract:
Image analysis from satellite imagery for mapping of coral at shallow water area is
important for knowing the habitat distribution and its changes. Satellite remote sensing
method for universal habitat-mapping has been shown to be cheaper (Mumby et.al.,
1997). Even though satellite image processing is a complex task but the outcome will
bring lots of use. In this study, image from QuickBird satellite for Bidong Island coastal
area year 2011 were used and it was processed using ENVI 4.7 software. A whole map of
coral distribution was produced and the coral cover at study area was detected where
52.46% of it is life coral, 21.31 % of dead coral with algae, 9 .84% of sand and 16.39% of
rubble. It is found from the changes of coral cover of Bidong Island coastal area 2007 and
2011 that life coral cover had increase by 19 .85%.
