This work aims to extract optical parameters of coastal sea water with high sediment and chlorophyll content by fitting reflectance spectra to a model. Sea-truth water sampling campaigns were carried out from Dec 1996 to Dec 1999 in coastal waters around Singapore. In-situ reflectance spectra were acquired using a portable spectroradiometer.

– The Worldview-2 satellite imagery with 2-m spatial resolution and 8 spectral bands is used to map the coastal ecosystems for our study site, an offshore island of Singapore. The eastern side of the study area is used as a landfill, while the western part of the island is left natural with rich biodiversity where large stretches of seagrass meadow,(More)
