The China Geological Survey Information Grid Platform has won the first prize for geographical and technological progress
Since the 16th National Congress, the China Geological Survey has organized and carried out geological survey work. With the acquisition of a large amount of geological survey data, how to promote information sharing to comprehensively serve society has become an urgent problem to be solved.
To solve this problem, many enterprises in the GIS field have fully tapped into the powerful data processing capabilities of GIS and actively applied them to China's geological survey data management. In July 2013, the project "Research and Application of China Geological Survey Information Grid Platform" jointly completed by the Development Research Center of China Geological Survey, China Geological Survey, China University of Geosciences (Wuhan) and other units was selected as the first prize of the "2013 China Geographic Information Science and Technology Progress Award".
This project relies on the "Digital Land" Land Resources Information Integration and Sharing Platform Construction (2006-2010) and the "863 Program" of the 10th Five-Year Plan of the National "Information Acquisition and Processing" theme "Resource and Environment Spatial Information Sharing and Application Services Based on SIG" project (2002-2005), the "Grid GIS Business System Construction" (2008-2010) key project of the 11th Five-Year Plan National High Technology Research and Development Program ("863 Program") Grid Geographic Information System Software and Its Major Applications, and other projects. After more than ten years of research and development, it has basically formed the China Geological Survey Information Grid Platform and the China Geological Survey Grid Node System, becoming one of the largest industry grids in China with certain service capabilities. It is also one of the important landmark achievements in the construction of geological information sharing platforms.
The platform has initially carried out the integration test of IMS SERVICE and GRID GIS WRSF SERVICE, proposed, designed and basically realized the technology and methods for establishing a peer-to-peer resource manager, initially achieved portal autonomy, node resource and portal resource sharing and collaboration; based on ontology theory, it has initially established a geological ontology classification and coding system, and initially realized the interconnection and interoperability of heterogeneous, cross-platform, and different GIS platform data; it has initially established a multi-node, multi-source data, multi-window data discovery mechanism, published data exceeding 1TB, and carried out demonstration tests of iron ore resource evaluation grid computing applications based on grid workflow technology.
Previously, the research results of the "Grid Geographic Information System Software and Its Major Applications" key project of the 11th Five-Year Plan in the Earth Observation and Navigation Technology field of the National 863 Program, completed by Zondy Digital Group, Peking University and other units, were widely applied in the China Geological Survey Information Grid Platform. This research achievement broke through core technologies such as distributed multi-source heterogeneous spatial data access and integration, global management, load balancing, spatial analysis and collaborative scheduling in grid environments. It successfully developed for the first time a large grid GIS software platform with independent intellectual property rights - MapGIS Grid, realizing heterogeneous GIS interoperability and online sharing services in grid environments. The overall performance reached the level of international similar software, and multiple technologies filled domestic and international gaps. The technical achievements greatly improved China's massive spatial data storage management level, large-scale distributed spatial computing capabilities, and resource service sharing capabilities, laying a solid technical foundation for technological innovation and renewal in China's spatial information field. It significantly enhanced the technical level and international competitiveness of domestic GIS software, promoting the innovative service and leapfrog rapid development of the domestic spatial information software industry. The achievement obtained 9 invention patents, 19 software copyrights, and published 135 papers. The results have been applied to 19 provincial nodes and more than 300 "digital city" constructions, carried out over 600 application services, generated indirect economic benefits exceeding 1 billion yuan, and had user visits exceeding 220 million, creating widespread social impact.
Today, the China Geological Survey Information Grid Platform architecture has provided strong technical support for the construction of multiple business systems, especially in the "China Geological Survey Data Network" as an important "window" for information sharing, greatly reducing repetitive development workloads and improving rapid development capabilities.
So, how is the application of the "China Geological Survey Data Network" supported by the China Geological Survey Information Grid Platform, and what services can it provide? With these questions, reporters visited the relevant responsible persons of Zondy Digital Group, a participating construction unit, and Li Chaoling, Deputy Chief Engineer of the Development Research Center of China Geological Survey. Through introductions from relevant personnel, reporters learned that in the first phase of the "China Geological Survey Data Network" project, more than 50,000 metadata entries were published, involving 9 major categories and 247 topics. Centered on thematic data services such as multi-scale geological map data and geological work progress, relying on MapGIS's powerful data processing capabilities and "Tianditu" geographic information as background, it provides a "5+1" service model consisting of 13 functional modules for both professionals and non-professionals:
First is the service based on international standard sheet geological maps. That is, supporting query operations on charts at different scales (1:1 million, 1:500,000, 1:250,000, 1:200,000, 1:100,000, 1:50,000), the system intelligently obtains geological map data at the same scale as the current chart and fills the query results into the corresponding area; second is the service providing geological maps based on geographic information. With "Tianditu" as the background, the system can perform spatial queries on a certain area of the geographic map layer to obtain all data information of the current area, and fill the data into the current query range; third is multi-topic directory query based on geographic information. Through spatial queries, the data resource directory of the current range can be obtained. To better display the data, a multi-window same-focus linkage mode is adopted for topic display, strengthening information comparison and facilitating information extraction; fourth is metadata directory query. Through keywords, metadata information can be queried and viewed, and graphic data can be quickly located or annotated to the corresponding position on the 3D earth; fifth is to provide POI services, that is, location and related information services; sixth is to provide functional API services. The platform provides API interfaces, which can conveniently integrate geological thematic data as base maps quickly into other application platforms.
Deputy Chief Engineer Li Chaoling said in an interview: "We hope to use new generation information technology to comprehensively display the achievements of China's geological surveys, comprehensively improve the information service level of geological survey achievements, and build the geological survey data network into a world-class 'window' of the China Geological Survey Bureau." The "5+1" service model has successfully realized the main functions of public welfare services of the China Geological Survey Data Network, effectively avoided duplicate investment, reduced "information islands" and "digital divide," powerfully promoted information sharing and efficient utilization, and enabled geological survey achievements to serve the public faster and better.
Today, with close cooperation among enterprises, government departments, research institutions, universities and other parties, GIS technology has been widely applied. Jointly devoting to the application research of China's geological survey information grid is the long-term solution to comprehensively improve China's geological spatial information sharing and application capabilities and levels.
