China News Service, Jinan, November 30 (Sha Jianlong) Li Chengjin, a second-level inspector of the Shandong Provincial Department of Natural Resources, revealed at a press conference held by the Department on November 30 that Shandong based on the existing basic surveying and mapping results, It will continue to enrich the data resources of surveying and mapping geographic information, give full play to the province’s “One Belt, One Road” East Asian economic hub, and increase the development and utilization of the “13th Five-Year Plan” results of surveying and mapping geographic information to better serve the ecological protection and protection of the Yellow River Basin. High-quality development.
Surveying and mapping geographic information is an important basic and strategic information resource of the country, which is related to national sovereignty, security and interests.
Shandong basic surveying and mapping work has a history of more than 40 years of construction and development, and has achieved a wealth of surveying and mapping geographic information results.
The press conference that day introduced the province’s "13th Five-Year Plan" surveying and mapping geographic information achievements.
According to Li Chengjin, during the "Thirteenth Five-Year Plan" period, the Shandong Provincial Department of Natural Resources, while completing the daily reception and archiving of surveying and mapping geographic information results, successively organized two provincial-wide surveying and mapping geographic information results collections, and achieved a wealth of results. The results of geographic information.
The collection of the results of surveying and mapping geographic information has effectively avoided "repetitive surveying and mapping" and has saved a lot of money for the country.
The development and utilization of the results provide strong support for serving the "two unification" management of natural resources, serving the economic and social development of the province and the construction of ecological civilization.
Li Chengjin said that Shandong has established the "12345" surveying and mapping geographic information resource system.
Tiandi·Shandong geographic information data resources continue to update, forming a new situation and new ecology of online services of geographic information resources; the province’s 1:10000 geographic information database realizes two-pass full-element update for the first time; geographic information spatio-temporal big data center, province The first-class natural resource satellite application technology center and the Beidou satellite navigation and positioning reference station network have been fully completed, forming three data service centers in air, space and ground; 4 elevation information data have been successfully acquired, and an elevation information database covering the entire land area of Shandong and offshore has been established; For the first time, the results of remote sensing images with a resolution better than 0.5 meters and the monitoring of geographical conditions have been updated annually.
Shandong has also promoted the transformation and upgrading of Tianditu·Shandong to the cloud service model, and formed a list of 129 government spatial geographic information special data services in 16 thematic categories.
The platform resources have served more than 50 areas at the provincial level, supporting online data sharing services for more than 3,000 business systems in Shandong.
Li Chengjin revealed that the Shandong Provincial Department of Natural Resources, in conjunction with the Zhucheng Municipal Party Committee and Municipal Government, has taken the lead in building a "picture" of rural revitalization in the country, exploring new models and new models that can be replicated and promoted.
In terms of "offline resources", during the "13th Five-Year Plan" period, an average of 69,000 pieces of graphics results of various types will be provided each year, more than 4,000 geodetic control points, and a cumulative amount of service data of 49TB.
In addition, Shandong's modern surveying and mapping benchmark system has been continuously upgraded, and a precise, efficient, autonomous and controllable Beidou satellite navigation and positioning reference station network has been fully established in the province; remote sensing image data resources have continued to be enriched, and 0.5-meter resolution aerial photography data has been covered annually. For the first time, the coverage of the airborne lidar point cloud data of the meter interval is better than that of the 0.05-meter remote sensing image in the whole province and the urban built-up area; the results of the geographic information database are dynamically updated.
Li Chengjin said that in the next step, Shandong will continue to actively promote the construction of geographic information spatio-temporal big data centers, seize new opportunities for the large-scale, popular, and standardized development of surveying and mapping services, and give full play to Shandong's “One Belt One Road” East Asian economic hub location advantages to promote Shandong's economy and society continue to develop rapidly, healthily and rapidly, and better serve the implementation of "digital empowerment", "digital Shandong", "perspective Shandong", "sky-land integration", and better serve the ecological protection and high-quality development of the Yellow River Basin and governments at all levels Decision-making, public management and people’s lives.
