Abstract Taking the WorldView-2 satellite data as sources, the author carried out depth study in the Xisha Islands, with the Zhaoshu Island and the South Island as test areas. The author first analyzed the correlation between the measured water depth and each band and then chose the most relevant band and band combination. It is shown that the coast band with green band ratio is the ideal combination for water depth extraction. Based on varying regression fitting analysis, the author determined the best fitting way that could achieve the best fitting precision in comparison with the real survey depth. At last, the model was used to conduct depth inversion of the South Island, and it is shown that water depth inversion root mean square error is less than 1.5 m, and the biggest relative error is within 0.26 m.
