| Abstract: | In this paper, a method of combining illuminated depth contour with color gradients was advanced, which realized the purpose of showing three-dimensional sea floor on two-dimensional chart. The means of deciding illuminated depth contour and color gradients were studied and corresponding model was established. Then the validity of this method was tested by experimentation. |
