Research on a data exchange center of land resources based on SOA

Spatial data exchange and system interoperate have become crucial technologies in land resources informatization. Due to the land resources data is accessed using a variety of GIS platforms, and the management systems are developed by different development languages, the data exchange model must support platform-independent solutions implemented in distributed heterogeneous environments. This paper proposes for designing a data exchange center by taking advantage of SOA technology and GML standard. The system aims to share and integrate various formats of spatial data with minimal time delay, providing a variety of services for interoperate between different systems. The proposed architecture is applied, as a case study, the data exchange center is implemented in Hunan province. In conclusion, the exchange between Hunan department and Changsha bureau shows that the application can achieve the goal in heterogeneous environments.
