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。 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.
