Seamless Integration of Spatial Information Grid with Heterogeneous Data Grid Using Broker-based Model

This paper discusses the special problems of spatial information integration and some features of broker-based data management model.We demonstrate the prototype of building broker-based model to integrate heterogeneous data grids,and managing transparent access to the related sources.The paper also describes our experiences of case study on seamless integration with Purdue tera grid data by using storage resource broker,which is based on the extensible data service interfaces of China spatial information grid.
