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)
