7月30日，由重庆市规划局组织、重庆市地理信息中心实施的重庆市地理空间信息共享交换平台项目通过专家鉴定，开始运行。

　　自2006年起，国家测绘局开始提出“数字城市地理空间框架建设与应用试点”项目，构建地理信息共享平台，实现各类信息互联互通，为政府科学决策、公共服务、社会管理、综合监督等方面提供框架支撑。并希望通过地理信息共享平台建设，解决数据资源规范化共享和低水平重复整合问题，加速地理信息公共服务平台建设，形成规范化的信息渠道、可持续更新的信息服务能力，促进部门间的信息共享，提升公共服务水平，加快空间基础设施建设和社会发展。

　　重庆市是中国西部地区和长江上游最大的经济中心城市，由40个区县（自治县、市）构成大、中、小城市有机结合的组团式网络化城市群，具有大城市带大农村的显著特征，是目前我国直辖市中行政辖区面积最大、人口最多、管理行政单元最多的特大型城市。推进重庆信息化建设，电子政务建设是不可缺少的重要因素，而地理信息作为政务管理的基本信息资源，统一标准，整合和集成资源是政务信息化管理的大势所趋。重庆市政府从各部门对地理空间信息整合、共享与交换的需求出发，提出了建设“重庆市地理空间信息共享交换平台”项目。其目的是基于统一的地理空间信息标准和规范，在一个公用的硬件和网络基础设施平台上，搭建统一的管理和整合公共基础性地理信息资源平台和空间数据库。通过地理空间信息共享交换平台，实现公共基础性的地理信息资源与政府部门专业地理信息资源的整合。并以此为基础，实现公共基础性的地理信息资源和政府部门专业地理信息资源的共享与交换，形成电子政务自然资源与地理空间信息基础数据库，构建地理信息资源应用服务与管理体系，为基于地理空间信息框架的人口、法人和宏观经济信息资源的整合与共享，为政府、企业、社区和公众提供地理空间信息服务，为建设“数字重庆”奠定坚实的地理信息资源和应用共享基础。

　　重庆市地理空间信息共享交换平台包括一套标准、一套共享数据库、一个共享交换平台和四个子系统。一套标准是重庆市地理空间信息共享交换平台服务标准与规范。一套数据库是包括政务电子地图数据库在内的一整套重庆市地理空间信息共享系列数据库。一个共享交换平台是包括近期的空间数据共享交换服务平台，以及远期的地理信息应用共享服务平台。四个子系统是为实现共享交换平台数据的共享与服务提供技术服务的支撑系统，包括开发地理空间信息数据管理子系统、共享交换子系统、公共服务子系统和运维管理子系统。它采用我国自主知识产权的Service GIS软件体系，形成基于“一张图”的区域资源整合共享模式，运用多级多源地理信息服务聚合技术、地理信息服务总线技术，建成了在线、准在线、离线的分布式部署与服务模式，实现了重庆市地理空间信息的集中与分布相结合的聚合、集成与应用，创造性地构建了一种新型的面向服务的地理信息共享模式，有效避免分头建设中出现的部门信息分割、重复投资、资源浪费等问题，为推动重庆市各部门地理空间信息共享交互，促进各类专业地理空间数据跨部门应用，提高政府工作效率奠定了良好基础。

　　重庆市地理空间信息共享交换平台的建设与运行促进了测绘从传统纸质地图、数据提供服务提升为在线地理信息服务，从以往的相对静态服务逐步发展为实时综合服务，有力地推进了测绘行业与地理信息产业的技术进步，对全国地理信息产业发展具有重要推动作用。

July 30, by the Planning Bureau in Chongqing, Chongqing Municipality GIS Center of Chongqing Municipality to share geospatial information exchange platform for project appraisal by experts, started to run.

Since 2006, the State Bureau of Surveying and Mapping the beginning of the "digital geo-spatial framework of urban construction and application of the pilot" project, building a geographic information sharing platform to achieve interoperability of all types of information for government scientific decision-making, public services, social management, integrated supervision provide a framework for support and so on. And hope that through the construction of geographic information sharing platform to address the standardization of data resources sharing and the integration of low-level redundant to speed up the GIS platform for the construction of public services, the formation of the standardization of information channels, sustainable ability to update the information services, and promote inter-departmental information sharing, to enhance the level of public services, to accelerate the construction of space infrastructure and social development.


Chongqing is China's western region and the upper reaches of the Yangtze's largest economic center city, from 40 districts and counties (autonomous counties and cities) constitute a large, medium and small cities in the organic integration of the group of urban agglomeration networks with large cities with significant rural areas characteristics of municipalities in the current administrative area of China's largest and most populous, the largest administrative unit of the large cities. Chongqing to promote information technology, e-government construction is an important and indispensable factor, and geographic information management as the Chief of the basic information resources, standards, integration and integration of government information resources are managed by the trend of the times. Chongqing Municipal Government from the various departments of geospatial information integration, sharing and exchange needs of the proposed building, "the Chongqing Municipal Geospatial Information Sharing Platform" project. Its purpose is based on a unified geospatial information standards and norms in a common hardware and network infrastructure platform, to build unified management of public infrastructure and integration of GIS and spatial database platform resources. Through the exchange of geospatial information sharing platform for the realization of public infrastructure of geographic information resources and government departments, professional integration of geographic information resources. And on this basis, the realization of public infrastructure of geographic information resources and government departments, professional geographic information sharing and exchange of resources, the formation of e-governance of natural resources and geo-spatial information database, build a geographic information resources application services and management system for geo-spatial information framework based on the population, corporate and macroeconomic information integration and sharing of resources for the government, enterprises, communities and the public with geo-spatial information services, to build a "digital Chongqing" lay a solid resource and application of geographic information-sharing basis .


Chongqing City, the exchange of geospatial information-sharing platform, which includes a set of criteria, a set of shared database, a shared platform and four subsystem. Chongqing Municipality is a set of standard geo-spatial information-sharing platform for the exchange of service standards and norms. A set of databases, including digital map database, including the Chief of the set of the Chongqing Municipal Geospatial Information Sharing Series database. Exchange of a shared platform, including the recent sharing of spatial data exchange service platform, as well as the long-term application of geographic information-sharing platform. Four sub-system is an exchange platform for the realization of shared data and services sharing the provision of technical services, support systems, including the development of geo-spatial information and data management subsystem, share exchange system, public service management subsystem and subsystem operation and maintenance. It is China's independent intellectual property rights of the Service GIS software system, the formation of "a map" to integrate the regional resource sharing model, the use of multi-level multi-source polymerization of geographic information services, geographic information service bus technology, built-line, quasi - online, offline and services distributed deployment model, the realization of the geospatial information in Chongqing with the focus on the distribution of the polymer combination, integration and application of a creative way to build a new service-oriented model of geographic information-sharing, effective way to avoid appearing in separate building sector information partition, repeat investment and waste of resources and so on, to promote the various departments of Chongqing geospatial information sharing interaction, and promote all types of professional inter-departmental geospatial data applications, to improve the efficiency of the Government has laid a good basis.


Chongqing City, the exchange of geospatial information-sharing platform for the promotion of the construction and operation of the mapping from the traditional paper maps and data to enhance the provision of services for online geographic information services, from the past, the progressive development of relatively static services for real-time multi-service, effectively promote the surveying and mapping industry and geographic information industries, technological progress, on the national geographic information industry has an important role in promoting development.
