Integration framework of multi-source heterogeneous spatial information and remote computing based on web services

To deal with the bottle-neck of enterprise distributed multi-source heterogeneous geographic spatial data´s interoperating, the four-tier integration framework of multi-source heterogeneous spatial information based on web services is designed. Through the integration of web services technology, the geographical information service criterion of OGC and the scalable vector graphics model (SVG) of W3C, the integrated device of spatial data translating services is constructed, which can realize the heterogeneous spatial data´s interoperating and showing by spanning the system´s heterogeneous and providing a kind of transparent loosely coupling relation between the users and the servers, service modules can be called through job scheduling services, lastly multi-source heterogeneous geographic spatial information can be integrated and remotely computed. It is primarily designed and applied in the State Earthquake Computing Application System (SECAS) based on the above framework and .NET platform, it realities multi-source heterogeneous geographic spatial data´s issuing and remote computing.
