February 14, 2014, organized by the National Surveying and Mapping Geographic Information Bureau Surveying and Mapping Development Research Center, "2013 Surveying and mapping geo-Information Blue Book Conference" held in Beijing. The experts introduced the connotation and development status of Wisdom Earth, wisdom China and Intelligent City, analyzed the position and function of surveying and mapping geographical information in the construction of intelligent China, and put forward the thinking, main tasks and safeguard measures of constructing intelligent Chinese geo-spatial intelligence system. The 2013-year survey of Geo-information Blue Book, "intelligent China geo-spatial Intelligence System Research Report (2013)" was officially released.

The Blue Book points out that in recent years, surveying and mapping GIS adapts to the latest trend of "intelligent earth" construction at home and abroad, implements the strategy of "constructing intelligent China", accelerates the transformation and upgrade of mapping geographic information, from retreat to landing, from concept to pilot, and promotes the construction of wisdom China, intelligent city

First of all, the "construction of intelligent China" as the mapping of Geographical information development strategy focus. At the end of 2012, the National Surveying and Mapping Geographic Information Bureau will "build up the Digital China, monitor the geographical situation, develop and enlarge the industry, and build a powerful surveying and mapping power" as the overall strategic adjustment to "build wisdom China, monitor the geographical conditions, strengthen the letter industry, build surveying power". Building Wisdom China is an important part of the transformation and upgrading of geographic information in the new period, and it is an important strategic measure to accelerate the pace of information construction, to promote the development of geographic information industry, to promote the transformation of geographic information production and service, and to enhance the ability of surveying and mapping geographic information service.

Secondly, the geo-spatial framework of digital China has achieved remarkable results and has been widely used in central, provincial and municipal areas, resulting in good economic and social benefits.

National geo-spatial framework is basically built. Mainly relies on the national modern Surveying Datum project, the western Mapping project, 1:50,000 Database Renewal Project, "The day map" and so on the important project implementation, realizes the surveying datum modernization, the geographical information data Update fast, the public service network. In the construction of surveying and mapping datum, based on the new technology of surveying and mapping, space positioning technology and network communication technology as the main technical means, the Foundation with stable Foundation, reasonable distribution and long term preservation is established through constructing, rebuilding and utilizing, forming a high precision, three-dimensional, The modern surveying and mapping datum system, which integrates dynamic and geometrical datum with physical datum. In the national basic scale topographic map surveying and updating, the western Mapping project achieved about 20% of the land area of China 1:50,000 topographic map of the "from scratch" and 1:50,000 database update Project to achieve about China's land area of 80% of the existing 1:50,000 topographic map data, "from the to excellent, from the old to the new." The complete completion of the two projects, achieved 1:50,000 topographic map of China's entire land cover. From 2012 onwards, the national surveying and Mapping Geographic Information Bureau to the national 1:50,000 key elements of the database updated 1 times, released 1 edition, to 2015, the National 1:50,000 database completed 1 comprehensive updates. With the development of this work, the comprehensive level of data achievement in our country occupies the international leading level.

Provincial-level geo-spatial framework construction accelerated implementation. In the construction of surveying and mapping benchmarks, 24 provinces (districts, municipalities) launched a real-time positioning accuracy of GNSS continuous operating benchmark station network construction, built 1244 base stations, 25 provinces (district, city) to carry out quasi geoid refinement, of which 23 precision up to centimeter level. In the basic geo-information database construction, 1:10,000 topographic map of the land coverage of 43.8%, 1:10,000 digital positive image coverage of 40.3%, 1:10,000 digital elevation model coverage of 40.1%, 17 provinces (district, city) to achieve 1:10,000 basic Geographic information data coverage of the entire region. In the construction of public service platform, 30 provinces (districts and cities) have completed the construction of the provincial node of the day map, which realizes the interconnection and interoperability with the "Day map" national nodes.

Urban (county)-level geo-spatial framework has achieved remarkable results. 2006, the National Surveying and Mapping Geographic Information Bureau launched the "Digital City Geospatial Framework Construction Demonstration" project, clarified the "One library (basic geographical Information database), a platform (geo-information public platform), 3~5 a typical demonstration application and a set of renewal and maintenance to promote long-term mechanism" construction content. Up to the end of 2013, the 321-prefecture-level construction project, completed 190, the development of more than 2,500 application systems, county-level has been established 260, the application of land, planning, public security, real estate, environmental protection, fire, health and other fields, in the economic and social development played an important role The work of the central financial investment of 400 million, local financial investment of about 6 billion, pulling service output value of 30 billion, because in many ways to achieve scientific and efficient management, avoid duplication of construction, save up to 10 billion.

The Blue Book defines the connotation and composition of intelligent Chinese geo-spatial intelligence system. Intelligent China's geo-spatial intelligence system is based on a large number of geographical information resources, with a new generation of Internet as the support, with the internet of Things, the perceptual network as the skeleton, the cloud computing and the big data for the blood, realize the integrated service and Intelligent application of geographic information, and provide the market service system Intelligent China's geo-spatial intelligence system consists of the following parts: "Large data" of surveying and mapping geographical information, surveying and mapping Geographic Information sensor network, surveying and mapping Geographic Information Intelligence Service, and corresponding policy standard system, safe operation environment, human resource guarantee, etc.

The Blue Book notes that intelligent China's geo-spatial intelligence system is a new subject for surveying and mapping geographic information, which not only requires a significant increase in the level of geo-information productivity, but also greatly improves the efficiency of geographical information service of surveying and mapping, and emphasizes the way to promote the intelligent operation and management of all walks of life. Construct the geo-spatial intelligence system which adapts to the construction and development of "wisdom China". To this end, "Smart China" geo-spatial intelligent system construction to adhere to demand traction + market regulation, Industry Promotion + Government support, project promotion + application of the overall development path.

The main tasks of intelligent China's geo-spatial intelligence system include the following four elements:

One is to strengthen the construction of large data. Accelerate the establishment of large data level, high information content of large geographical information data resources, the realization of geographical information resources "more complete", "more refined", "more detailed", "Update", in order to promote the mapping of geographical information services to intelligence, intelligent transformation and upgrade to lay a solid foundation.

Second, to strengthen scientific and technological innovation. vigorously promote the geographical information acquisition, processing, management, service and other aspects of the independent innovation of technology, strengthen the geographical information technology and modern High-tech integration and integration, for the establishment of surveying and mapping Geographic Information sensor network, mapping geographical information intelligent applications to provide an important technical support.

Third, strengthen the intelligent infrastructure and equipment. Full introduction, absorb the scientific and technological achievements in the field of information, strengthen the construction of the key surveying and mapping geographic information infrastructure and equipment, realize the real-time acquisition, efficient processing, rapid response and security application of geographic information, and provide reliable and powerful infrastructure and equipment guarantee for promoting the wide range, omni-directional and deep application of intelligent applications.

Four is to strengthen the wisdom of application. Adapt to the network, information and intelligent development trend, strengthen the knowledge storage of surveying and mapping geographic information service products, accelerate the intelligent transformation and upgrade of geographic Information service mode of surveying and mapping, promote the deep application and intelligent application of surveying geographic information in various fields of economic and social development, and effectively promote the construction of intelligent city and wisdom industry.

Finally, the blue Book points out that the development of intelligent China's geo-spatial intelligence system should do well in top design, pilot demonstration and popularization, establish surveying and mapping geographic information cloud gradually, set up surveying and mapping Geographic Information sensor network, and quicken the pace of construction of geo-information resources. At the same time, in supporting policies, standard support, innovation mechanism, personnel training and so on to do a good job.
