| Abstract: | Using the GIS theory and thinking,the format of measuring data of water depth is analyzed,and a new method to organize and manage the measuring data of water depth with spatial database is presented and data structure is given.The value of the measuring data of water depth is deeply mined on this basis,and a way to model the terrain underwater with discrete point data is presented to realize the expression of 3D visualization of water depth.At last,the process of terrain modeling,the steps of color rendering and the optimization method of 3D scene are given. |
