Abstract


Over the past fifty years of Changbai mountain and northeast Asia scientific research, people accumulated a lot of scientific data. However, these data are different between sources, phase, scale, and properties, limited comprehensive and multi-source information integration applications. With the information time is approaching, this sharing platform for people to interact in the form of information recognized by more and more attention. To avoid data silos, systems and business silos island emergence of sharing platform in China are accelerating the pace of construction, Shan xi, Liao ning and other provinces have set up their own provincial geographic information sharing platform.For Changbai Mountain region multi-source spatial data heterogeneity, this paper analyzes the spatial heterogeneity of the main performance and the traditional way of major data integration. From a view of Spatial data integration, to presents a multi-level framework for spatial data in Changbai Mountains, to metadata, uniform standards and classification system for spatial data integration framework, and program design as a framework for spatial data based on WEB Service Sharing platform.Paper, based on service-oriented Architecture, in accordance with the hierarchical thinking of the overall structure of the system is designed and conducted a service-side design. The Platform used large number of advanced technology of current WEBGIS applications. combined with the RIA rich client development, silverlight / WPF technology, and ArcGIS Server-based platform WEB Service, greatly enhancing the platform’s application experience. Instance of the system achieved the use of raster data and vector data overlay, animation, multimedia integration, transparency control, map perspective and other functions, the system runs smoothly smooth, without a page refresh to the browser quickly, accurately and spatial data display Take full advantage of purposes. Finally in the business data safe and secure circumstances, the results show the full share.
