Abstract

Virtual Geography Environment (VGE) is a comprehensive subject concerning remote sensing, geography, information theory and communication etc. There have multi-source, diff-structure, interdiscipline, and inter-organizations data related to VGE. Moreover, the tasks in VGE will cover many aspects inevitably. In order to complete the task proposed by user, it is required to integrate, link and share the distributed data in different organizations or domains. But it is almost impossible to solve many problems by using traditional ways such as changing some kinds of data structures which has formed standard. The advent of the third network technology, Grid, gives VGE new dimension of development. Grid has some hard core functions, such as shielding diff-structure data, harmonizing resource-sharing and cooperating with each other in virtual organization to complete the task. Based on the Grid and VGE, the Grid Virtual Geographical Environment (Grid-VGE) is put forward, which abides by the standard of Open Grid Services Architecture (OGSA), takes Services as core and constructing virtual database. In order to link, integrate and share all required data, we abstract all data into metadata and description to interlink through link based on the standard of OGSA. The proposed data structure method can absorb any data anytime while not modifying the original data and it will enlarge and increase efficiency of the application in VGE.
