Abstract: This paper focuses on terrain visualization service and proposes its service architecture. Meantime we also study on the implemention mechanism, data management and service management in system. Several key problems, such as program design and LOD (level of detail) algorithm, are discussed to improve real-time rendering efficiency under Java environment. Finally, the paper designs and implements a prototype system, which show that the algorithm is practical and efficient.

Key words: Services, Terrain visualization, Grid, Level of detail (LOD)

摘要： 以地形可视化服务为目标，建立地形可视化服务框架，研究服务运行机制、数据资源代理和服务管理等关键技术。该文研究了Java环境下的地形实时可视化程序设计和细节层次模型简化等关键问题，设计和实现了一个简单的应用案例, 给出了实际测试的结果，验证了该框架的有效性。
