【摘要】：地理信息公共服务平台是数字城市地理空间信息框架建设的核心任务，是实现地理空间框架应用服务功能的数据、软件及其支撑环境的总称。平台的建成将优化人们的生产、生活方式，加快城市建设与发展的步伐，促进经济健康发展和社会全面进步。本文依托数字葫芦岛地理空间框架建设项目，开展公共服务平台专题研究。论文的主要研究内容及研究成果如下：1，分析了国内发展现状，并重点研究了“3S”集成技术、海量地理空间数据库技术、面向服务软件架构等支撑数字城市建设的关键技术；2，研究设计葫芦岛市公共服务平台的总体架构、数据库结构以及支撑子系统的功能结构，基于面向服务架构（SOA）建设了葫芦岛市公共服务平台，并设计出数据库管理系统以及三个子系统，实现对服务平台的运行、维护，对数据资源的管理、更新以及服务资源的集成、发布；3，采用微软Silverlight技术开发了数字葫芦岛公众服务系统。基于REST风格架构对数据资源进行服务抽象，调用服务结合算法实现公交换乘功能；4，通过调取公共服务平台的地图服务，结合工商专题数据，，利用REST定义Web服务应用程序编程接口（API），实现工商信息管理系统。通过性能测试，公共服务平台完成了预期目标，取得了良好的效果。
[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.
