KARAKTERISASI 3D SUBSTRAT BENTIK PERAIRAN KARANG PULAU BONETAMBUNG MAKASSAR
ABSTRACT: The objective of
this study is to characterize benthic substrate of Bonetambung reef area using
worldview 2 high resolution satellite imagery. About 14.273 depth spot were
deploy to build bathimetric model of the study area. The correlation of pixel
radiance value from satellite imagery and depth value from field measurement
were became the basis to classify geomorphologic zone of shallow water area up
to 7 meter depth. Between three interpolator tested, the natural neighbor
interpolator has produced the best bathymetric model with root mean square
error 0.3 meter and benthic substrate coverage model with thematic accuracy
62%. These approach be able to recognize four substrate type in general, such
as sand, seagrass, rubble and coral. Geomorphic segmentation based on
bathymetric profile and radiance value of worldview 2 imagery may also maps the
reef flat, reef slope and lagoon area hence may support the benthic substrate
modeling. This study showed us a potential technic to develop a modelling for
juvenile fish transport at Bonetambung coral waters.
