As the development of front-end monitoring equipment, real-time communication and the back-end database management system, the system integration of various units have always troubled the system developer. The system integration include systems developed in different years for the same department, data flow from different departments, different attribute data from various monitoring systems, and the data for supervising organization. Furthermore, the data integration was no longer data itself but also the spatial information need to integrate. In order to solve the abovementioned problems, the key is to adopt an international standard for data flow and exchange, such as the standard architectures based on the open technology proposed by the ISO/TC211 (International Organization for Standardization/ Technical Committee 211) and the OGC (Open Geospatial Consortium). Both standard architectures are gradually mature and adopted in the spatial information infrastructure in many countries. The software company or non-governmental organizations are also actively developing software that support open technology, can be expected to play an essential role in the information flow and applications in the Internet.
Hydrological automatic monitoring system contain temporal data and spatial geographic information, the standardization work should be focused in the currently mature standardization of space information. The government has promoted the “Data exchange and sharing standard for land information system” since 2004, and re-planning the land geographic information standard system development strategies, using the ISO/TC211 and OGC developed geographic information standards as based environment, to enhance the data circulation and interoperability among systems in the open land information system.
Therefore, this study is largely based on the idea of standardization for the spatial hydrological monitoring data standardization, to design a middleware illustrating and proving the feasibility of standardization documentation among Irrigation Association and other agencies and to provide the important reference for the circulation of the hydrological spatial data exchange. The creation of data standardized system and open interfaces through open geographic information system (Open GIS) specifications, and support interoperability is the solution to the spatial data integration.
