Accurate inversion of shallow water depth is essential for marine space management and ecological environment protection. Lingyang Reef of Xisha Islands in the South China Sea is taken as a typical study area. The single-band model, multi-band model and band-ratio model are established based on GeoEye-1 and WorldView-2 high-resolution multi-spectral remote sensing data and measured points. The results show that the correlation of the inversion model established with the participation of green band is generally high, while the multi-band model established by four bands combination has the highest accuracy and the correlation coefficient reaches 0.870 and 0.853, respectively. Comparing with the inversion accuracy of GeoEye-1 and WorldView-2 data in different depth ranges based on the above model, the conclusion is that the inversion errors of the two kinds of data in different depth ranges have the same trend, with the maximum value of the average relative errors occurring in the range of 0−5 m and the minimum value occurring in the range of 20−25 m. In general, the inversion accuracy of WorldView-2 image is higher than that of GeoEye-1 image. This study has a certain reference significance for the inversion of water depth in shallow tropical sea.
