| Abstract: | Aiming at technical difficulty of bathymetric data's storage and visualization,a technique based on the model of level of detail is presented in this paper.By using this technique,we can deal with the bathymetric DEM effectively.At last,the experiments show that the algorithm of LOD is very good for bathymetric DEM visualization. |
