Abstract: High-resolution optical sensors onboard satellites such as Pleiades provide important tools for environmental assessment of coastal areas. The advantages of satellite imagery include rapid acquisition of images covering large areas, the repeatable viewing of the satellites over almost any part of the globe, using different spectral bands and sensing data without any contact. The beaches environmental assessment and coastal health is a complex phenomenon dealing with a variety of issues including pollution prediction, investing in health and methods research, strengthening beach standards, improving public health and environmental protection for people living near the coastal area, and providing the public with information about the quality of their beach water. An efficient method for monitoring the health of coastal areas is to assess seawater health, because the main characteristic of coastal areas is their proximity to seawater. The remote sensing techniques can be used to monitor water health by incorporating spectral bands. The Costal Color Monitoring (CCM) provides radiance measurements in visible and near infrared bands with higher spatial resolution. The "color" of the ocean in satellite images comes from substances in the water, particularly phytoplankton (microscopic, free-floating photosynthetic organisms), as well as inorganic particulates. Because ocean color data is related to the presence of phytoplankton and particulates, it can be used to calculate the concentrations of material in surface waters and the level of biological activity. In addition, monitoring surface color for coastal areas is a critical task that should be considered for precise and accurate estimation of water health in onshore and offshore area. This study describes the main steps required for sea color extraction in coastal case 2 waters using high-resolution satellite imagery from Pleiades.
