Coral mapping are crucial in today’s research as the information can be interpreted
into other information. Studied on coral mapping was conducted at southest area of
Pulau Bidong, focused on an area between Pulau Bidong and Pulau Karah using
multibeam echo-sounder. For monitoring on coral reefs, a bathymetric map is useful
as a base to locate vulnerable areas. This study uses high resolution multibeam
bathymetry, bathymetric derivates, and in situ data in a geographic information
system. Detailed bathymetry data from quantitative descriptors of the seabed terrain
were obtained such as Bathymetric Position Index (BPI) and slope. Accuracy
assessment use ground-truth were performed through Coral Video Transect (CVT)
technique. The results introduce a new classification scheme that may suitable for
developing maps pinpointing high biodiversity around coral reefs. Besides, the coral
growth forms or morphology were computed from Coral Point Count with Excel
extension (CPCe)
