Distributed Spatial Data Management

摘要

The complexity of spatial data management will be high as the volume of spatial data increases rapidly. As the emerging technology, it is an innovative method that grid computing technology is applied to manage geographically distributed, autonomous and heterogeneous spatial data. Integrating grid computing with spatial data management technology, the authors designed a basic but high extensible framework for managing distributed and large-scale spatial data. In this paper we put emphasis upon spatial metadata service design and spatial data grid design.
