數(shù)字葫蘆島地理信息公共服務(wù)平臺研究與建立
[Abstract]:The geographic information public service platform is the core task of the construction of the digital city geospatial information framework. It is the general name of the data, software and its supporting environment to realize the application service function of the geographical space framework. The completion of the platform will optimize people's production and lifestyle, accelerate the pace of urban construction and development, and promote healthy economic development and overall social progress. Based on the digital Huludao Geospatial Framework Construction Project, this paper carries out a special research on public service platform. The main research contents and results are as follows: 1. The present situation of domestic development is analyzed, and the integration technology of "3s" and the technology of massive geospatial database are studied. Service-oriented software architecture and other key technologies to support the construction of digital city; 2. The general structure of Huludao public service platform, the database structure and the function structure of supporting subsystem are studied and designed. Based on the service-oriented architecture (SOA), the Huludao public service platform is constructed. The database management system and three subsystems are designed to realize the operation and maintenance of the service platform, the management and updating of the data resources, and the integration and release of the service resources. 3. The digital Huludao public service system is developed by Microsoft Silverlight technology. The data resource is abstracted based on REST style architecture, and the bus transfer function is realized by calling the service combined with the algorithm. 4. By taking the map service of public service platform and combining the special data of industry and commerce, we use REST to define Web service application program interface (API), to realize the business information management system. Through the performance test, the common service platform has achieved the expected goal and achieved good results.
