| Abstract: | The article is based on the method of relief-shading map as well as combining with the actual situation of the marine geographic data. It has discussed the making method of three-dimensional submarine shaded relief map. And we apply this method to the projects related to the marine basic geographic data-atlas of the production of geographical entities. Using GIS software, the computer can automatically create the seabed shaded relief map of the three-dimensional. As can be seen from the final results ： plan and perspective view has a very strong three- dimensional sense. This enables people to have an intuitive understanding of the seabed topography, convenient application. |
