【 摘 要 】

This study identified the performance of Lyzenga water column correction under controlled condition of noise, water quality, and bottom type diversity. We build a simulated multispectral imagery, represent the subsurface reflectance of coral reef environment that receives by Worldview-2 satellite. The evaluation was performed to two different subsurface reflectance: Lee et al.'s and Maritonia et al.'s radiative transfer model. As a result, in the case of simple Maritonia et al.'s reflectance model, it shows that the effect of the water column is removable. However, if the actual just above surface reflectance is as more complex as Lee et al.'s model, then the Lyzenga's water column method could reduce the effect of water attenuation but not removed. In fact, based on the mathematical presentation of Lyzenga's model on simulation reflectance formula the effect of depth and water attenuation are in multiplication function. Thus, even after the correction, the water column attenuation effect stillremain.
