The Research And Practice On Construction Of Commom Platform Of Geographic Information

Geographic information public platform is the core component of Digital City. Based on fundamental geographic information, it integrates with information and data of multi-industries. By providing online services, it meets government departments, enterprises and institutions and the social public's needs of geographic information and spatial orientation and analysis. In the meantime, it satisfies the basic requirement of other industries about constructing professional application system related to their own feature expediently as well. However, the construction of geographical information public platform is a complex and huge project, involving computer science, network communication, GIS technology etc. According to different situation across the country, undergoing and completed geographic information public platform construction projects in different places varied in their construction plan and method, which are directed affected by apparent differences existing among project funds and original resources owned by the local government. Thus, studying the construction content and structure is instructive to specific implementation of geographic information public platform construction.First of all, the content and structure of geographic information public platform construction is explored. Abiding by criterion of geographic information public platform released by the State Bureau, geographic information public platform dataset,exchange management and online services system is analyzed in detail. Technical functional architecture of geographic information public platform is studying and service standard obeyed by platform service function is simply introduced.Secondly, in the context of Yulin geographic information public platform construction, overall architecture, subsystem functions of the geographic information public platform is designed. Adopting service oriented architecture, the platform designed a portal subsystem, management subsystem and data maintenance sub-system to realize the functional needs including online services, data exchange, maintenance and so on.Data management of the platform is designed. The mass, multi-sources and scale data is organized in an order and reasonable way to establish fundamental geographic information database. As a necessary part of geographic information public platform, sharing database is designed, reprocessing the fundamental geographic information data and providing service oriented product dataThrough the research and practice of the geographic information public platform construction, individual opinion and experience is summarized and available for relevant project construction as reference.
