摘　　要：地形三维化是近些年随着地理信息系统和计算机可视化技术发展起来的新兴应用。现阶段地形可视化的研究对象还主要集中在陆地地形,对于水下地形的研究很少。论文中介绍了一个基于二维电子海图中离散水深数据通过分形曲面插值算法构建数字高程模型(DEM),并通过三维地形建模最终实现海底地形的三维可视化的解决方案。With the rapid development of Geographic Information System and Computer Graphics,Terrain Visualization become a real technology.The research on Terrain Visualization focuses on land in the present,which means there is little study on seabed topography.A Terrain Visualization solution consist of a digital elevation model(DEM)based on fractal interpolation,which is constructed from discretely depth data extracted from two-dimensional electronic chart,and realization of terrain three-dimensional modeling is proposed in the paper.
