The data for establishing digital basin has the features of large quantity, heterogeneity and multiple dimensions. Determining how to effectively manage and share the data is the key for digital basin. This paper shows an information sharing model for digital basin based on metadata directory, Service-Oriented Architecture (SOA) and publishing/subscription technology. And then, for easily transmission, we preliminarily accomplish the data conversion based on Geography Markup Language (GML).

Encryption Method

This paper analyzed the typical architecture of geographic information sharing system based on GML spatial data, pointed out the security risks existed in the network transmission process of the GML spatial data and drawbacks of the existing security transport mechanisms in such a shared system. Further, the paper elaborates on advantages of encrypting the GML data using XML Encryption technology and the encryption process of the GML spatial data. On this basis, the paper gives an application example which encrypts all or part of spatial data in GML documents by the XML Encryption technology.
