Abstract
Virtual Geography Environment (VGE) is a multi-subject which includes Geographic Information System (GIS), Remote Sensing (RS), Virtual Reality (VR) and network etc. It is inevitable to include a lot of different structure, transdisciplinary and inter-organizations data. With the deep development of VGE, the VGE hopes to attain a primary goal, which deals with geographical data by integrating, storing, indexing, operating and analyzing to get kinds of decision-making information. It makes traditional network service lag behind the development of VGE, because there are some shortcomings in network technology at present such as limited bandwidth, a lot of data exchanging in different organizations, and hard to ensure resource sharing adequately. Grid, as the third generation network, brings new vigor to VGE. It gives a more progress to VGE by combing Grid. Grid-VGE, which 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 different structure data, decomposing the task, using the disengaged resource fully and extending the services in VGE. After expounding the framework of Grid-VGE in detail and its pivotal technology, and application example will be given in the last.
