Abstract:A quantitative technique for shallow water bathymetry has been described and evaluated in this paper. First,the information of the bottom type was extracted by analyzing multispectral characteristics of remote sensing images for some well-known points.Second,on the basis of the identification of coral stone and sand,image calibration brightness logarithmic values were selected from the imagery for locations of water depth measurements and two regression curves were established, which can be used for water depth prediction in other areas based on imagery from similar limpid environments.The results prove that the performance is satisfactory in shallow water and suggest that with further refinement the technique can be used to give a quick comprehensive estimation of shallow water depths.
