Web service directory is an important component of SOA-oriented urban spatial information sharing platform. The current UDDI and UDDI-based UBR have been poorly used actually. One the one hand, the business services of urban spatial information sharing platform have some characteristics such as diversity, complexity and security, so the increase of web(More)
In order to break the bulwark and eliminate the information isolated island in UGIS, the architecture of SOA-oriented urban spatial information platform is proposed. The SOA-oriented urban spatial information management and service architecture is designed and the key technologies are discussed in detail. The architecture is based on service and adopts the(More)
UDDI (Universal Description, Discovery, and Integration) is a directory to register and locate web service application. It facilitates businesses to easily and dynamically find and transact with one another through their preferred services. The present centralized UDDI structure is less robust and it is difficult to support a large number of Web services.(More)
With the wide application of spatial information grid, how to solve the data synchronization has become a current research focus in spatial information grid. Because of the confidentiality and specificity of spatial data, it needs each grid node can only have their own data. When one grid node wants to use the data in another one, it must obey the principle(More)
This paper analyzes the characteristics of geological spatial information sharing at first. In order to break the current “information island” and implement spatial information sharing among virtual organizations, the concept of China geological spatial information grid is proposed. Focusing on the core techniques of grid virtual and(More)
