Building data infrastructure for geo-computation by spatial information grid

摘要：

The continuing research on geo-computation purchases more orders to the data infrastructure of geocomputation. It should be distributed, platform-independent,extensible, robust, autonomic, and can on-stop serve the users and applications. In this paper, based on spatial information grid (shortly SIG), a 4-layered data infrastructure which is built up by data nodes, data sources, data agencies, support libraries, and other components is proposed. It adopts an XML based extensible data accessing language as the operating protocol for the data sources and data agencies.Furthermore, some primary data sources and data agencies are designed and implemented; and based on them, a prototype of the data infrastructure is constructed and tested.The test shows that the SIG based data infrastrucure can provide different sources, types and formats of spatial information data and make it easier to build up application for geo-computation.
