摘　　要：S-57是HIO"数字海道"测量数据传输的标准,已成为全球海道部门进行信息化管理的重要手段.随着三维建模及可视化技术广泛应用于海道信息化建设,如何利用S-57海道数据实现三维可视化是"数字海道"有待解决的问题.基于S-57标准建立海道数据三维可视化模型,利用空间插值技术,优化数字海道的三维地形数据,同时建立三维对象的实时数据交换接口,真实反映海域内船舶的航行状况及电子海图对象的空间信息,为船舶监控、海上营救和海事管理提供重要的参考依据.S-57 is the HIO standard for digital hydrographic data,which now has become an important means of information management for the global hydrographic departments.Additionally,the technology of 3D modeling and visualization has been widely used in the information construction of the hydrographic management.And it is urgent to work out the technical issue in the maritime management system as how to extract the useful information from the S-57 format data and realize the 3D modeling and visualization.In order to solve these problems,this paper presents the model of 3D visualization of the sea based S-57 standard,using the spatial interpolation techniques to optimize the three-dimensional terrain data of the digital hydrographic management,providing the interaction interface of 3D objects,truthfully displaying the sailing condition in the sea area and electronic chart object＇s spatial information,which offers an important reference to the sea rescue and the maritime management.
