Paper Abstract

In order to implement some kinds of spatial data center system in the grid GIS environment, we need to introduce the concept of grid spatial data center (GSDC). This paper presents the basic architecture of GSDC, which is the research focus of this study. GSDC architecture is based upon and extended from the grid GIS architecture, considers and absorbs the important characters of traditional distributed spatial data center (DSDC). The key techniques and mechanism of DSDC, such as multi-hierarchical spatial data exchange and update, and inhomogeneous data seamless integration, are reconstructed to become the essential services of GSDC in a new form. This paper is also a contribution to achieve an approach to implement such system, and we discuss the various applications of GSDC in appropriate occasions. First of all, this paper analyzes the traditional distributed multi-hierarchical spatial data center architecture in detail, and indicates the senseful ideas and inherent bottleneck problems of it. Then, it gives some advantages come from the developing grid GIS, which can solve the bottleneck problems of DSDC mentioned previously. After presenting the desirability of combining these two powerful things together, this paper analyses the essential services to compose GSDC, which come from the decomposition of the traditional multi-hierarchical DSDC. The original normal modules are transformed into services, and provide their well defined standard function into grid. This paper also gives out the framework of establishing multi-hierarchical virtual organization in GSDC, which is the infrastructure to satisfy the geographical distribution of the using organizations, and the resource sharing and exchange between them. Then, it deals with implementation aspects, and indicates that smooth upgrade from DSDC to GSDC is very important to the application of GSDC. In conclusion, this paper concludes that grid services can give the necessary specifications and standardizations to implement spatial data centers, and can improve the collaboration between them. The disadvantage factors in development of GSDC are also discussed.
