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.

In this paper, we present a semi-automated approach to high quality three-dimensional (3D) objects reconstruction from single high-resolution satellite image using monoplotting technique. The method requires high accuracy of satellite sensor model, such as Rational Polynomial Coefficients (RPC), and high resolution of Digital Elevation Models (DEM) to(More)
