Space Based On Ogc Specifications, Information Sharing Services Research

With GIS technology, computer technology and Internet network technology represented by the rapid development of GIS application leap to the Internet Age, in the realization of space on the Internet information-sharing and interoperability functions, GIS is the inevitable trend of development.Based on the analysis of domestic and international information sharing space research, and in view of the current application of the space information-sharing issues, based on OGC we has proposed the establishment of norms of space-based information service system. And made the following aspects related to research and explore:1,Introduced the concept of Web Services technology, features and system framework.2,Introduced the details of OGC Specifications and the technology of GIS Interoperability.3,Explored the relationship between the spatial information sharing and the construction of Digital City, and Discussed the approach of which used ArcGIS Server architectured spatial information sharing platform,and Introduced on the building of Kunming's integrated geospatial database.4,Based on the existing problems of current information sharing space and the practical application of experience, we has proposed the establishment of a service-oriented space-sharing system--Based on OGC standardized spatial information sharing services.Based on OGC standardized spatial information-sharing services is a new area of research, it can be said this is the distributed computing technology WebGIS system and the direction of development, but also the future of digital urban construction one of the key technologies. Its future development trend will be more open GIS system, with the OGC standards, as well as the constant improvement in the continued support of commercial software, service-oriented applications will be information sharing space GIS industry as a whole, particularly spatial information sharing and Digital City have aprofound impact on development.
