抄録

Multispectral remote sensing of coral reef bathymetry by popular Lyzenga et al.(2006)'s method theoretically becomes more accurate with increasing number of bands used. The recently-appeared WorldVIew-2 imagery has doubled number of bands compared with the traditional high-resolution satellite imagery. In this study, we validated the accuracy improvement of Lyzenga et al.'s method by the doubling of bands through its application to five WorldView-2 images of four coral reef sites. As a result, for all the images, the adjusted R squared value of the water depth estimation function improved by doubling the number of bands used, although the degree of improvement (0.003 at the minimum, and 0.097 at the maximum) differed among sites, and even between the two images of a same site.
