【摘要】：地理信息资源是涉及国家安全、经济社会发展的基础性和战略性的资源，它整合了各类自然资源信息和经济社会人文信息。随着政府管理决策科学化、经济与社会发展信息化以及和谐社会建设的不断推进，政府部门、企业和社会公众对地理信息服务的需求与日俱增。然而当前，基础地理数据的离线提供仍然作为数据共享的主要的方式，这种方式环节多、周期长、应用系统构建技术复杂、成本高，导致用户无法获取持续更新的数据，也不能满足大规模业务化应用需要。地理信息公共服务平台，旨在建立规范的空间数据标准化体系，通过空间信息资源的交换与共享，，联通水利、交通、国土、规划、气象、环保等业务部门，为政府机构、企事业单位、社会公众提供在线地图服务和专业信息服务，从而全面提升城市信息化公共服务水平。本文描述了地理信息服务发展的现状和趋势，分析了城市信息化建设对地理信息有效整合、交换和共享的需求，提出了北京市地理信息公共服务平台建设的关键技术和实现方法，并从标准规范方面、数据库方面、功能方面对平台进行了总体设计，继而对平台建设的实现过程进行展开，完成了具有空间服务、GIS门户、数据管理和运维管理功能的代表性地理信息服务平台的建设。本文主要成果如下： 1.基于地理信息共享的目标，探讨了海量空间数据统一存储、管理、更新及应用的标准与技术体系，保证了共享数据的时效性、权威性。 2.基于面向服务的架构（SOA）技术，分析了地理信息共享服务平台的关键技术与技术路线，采用服务的模式实现了地理信息资源的共享。 3.以北京市为例，初步实现了地理信息共享服务平台的基础功能。
[Abstract]:Geographical information resources are basic and strategic resources related to national security, economic and social development. They integrate all kinds of natural resources information and economic and social human information. With the development of scientific government management, the development of economy and society and the construction of harmonious society, the demand of government departments, enterprises and the public for geographic information services is increasing day by day. However, at present, the offline provision of basic geographic data is still the main way of data sharing, which has many links, long period, complex technology of application system construction and high cost, which results in users unable to obtain continuously updated data. Nor can it meet the needs of large-scale business applications. The geographic information public service platform aims to establish a standardized system of standardization of spatial data, through the exchange and sharing of spatial information resources, the connection of water conservancy, transportation, land, planning, meteorology, environmental protection and other business departments, for government agencies, Enterprises and institutions, the public provide online map services and professional information services, so as to improve the level of urban information public services. This paper describes the current situation and trend of the development of geographic information service, and analyzes the demand for the effective integration, exchange and sharing of geographic information in the construction of urban information. This paper puts forward the key technology and implementation method of the construction of Beijing Geographic Information Public Service platform, and designs the platform from the aspects of standard specification, database and function, and then carries on the implementation process of the platform construction. The construction of representative GIS platform with the functions of spatial service GIS, data management and operation and maintenance management is completed. The main achievements of this paper are as follows: 1. Based on the goal of geographic information sharing, this paper discusses the standard and technical system of unified storage, management, update and application of massive spatial data, which ensures the timeliness and authoritativeness of shared data. Based on the (SOA) technology of service-oriented architecture, the key technology and technical route of geographic information sharing service platform are analyzed, and the sharing of geographic information resources is realized by service mode. 3. Taking Beijing as an example, the basic function of geographic information sharing service platform is preliminarily realized.
