| 摘 要： | 通过将网格技术与虚拟地理环境结合,以服务为核心,构造虚拟数据库,形成网格虚拟地理环境(G ridV irtual Geograph ic Environm ent,G rid-VGE),实现异构数据的集成与共享、任务的分解、闲散资源的充分利用、扩充虚拟地理环境的服务等。在详细阐述了G rid-VGE的框架结构及其关键技术的探讨后,以三维可视化地形漫游为例展示G rid-VGE中的一个应用实例。

| Abstract: | With the combing the Grid and VGE,the Grid Virtual Geographical Environment(Grid-VGE)is generated.It abides by the standard of Open Grid Services Architecture(OGSA),takes Services as core and constructing virtual database.It can achieve the functions such as integrating and sharing the diff-stusture data,decomposing the task,using the disengaged resource fully and extending the servers in VGE.After expounding the framework of Grid-VGE in detail and its pivotal technology,an application example is given at last. |
