As a key part of the national space information infrastructure, the geography space frame of Digital China is the basic supporting platform of national economy and social informatization. With the continual development of the geography space frame construction of Digital China and the accumulation of the basic geography information resource, how to integrate the information under a uniform standard, to exchange information in the frame of policy, law and regulations, to share and provide public service become the present highlights.According to practical experience, the thesis chooses the city level GIS service sharing platform as the objective, which is based on the national political information resource exchange system standard and the actual situation of the informationization. Planning from an overall view and following the concept of constructing integration of information resources, the thesis determines the content and objective of the platform, which is building a portal site, a data center, a group of geography space information resource database, five application service software and five support systems.Then the thesis provides a detail solution to build the system according to the architecture of the platform. The multi-resource space data integration and sharing on the heterogeneous platform is realized by using SOA architecture, following OGC standard, using advanced database technology, network technology and ESB integration technology under the support of ArcGIS, the new generation large scale GIS platform.Furthermore, the thesis discusses the method of effective management of the multi-source and massive space data from three aspects including the data structure and classification, data organization, database structure design. The thesis makes a detailed division of the basic geography data and data set and provides a suitable organization for different data types. The whole database structure uses the mode of central node plus sub node, that is the combination of centralized and distributed mode.Finally, focusing on the view of rapid data display, the thesis illustrates using the mainstream technology, map slicing, to achieve effective data release and access. From the view of space data quality management, the thesis represents the solution of inconsistency in space data format and the differentiation of data standard.
