Scientific layout

The "5+1" major project to form a new pattern of high resolution special data and application of high-resolution Earth observation system (referred to as the "high score project"), like the Human spaceflight project and the lunar exploration project, is one of the 16 major projects identified in the national mid - and long-term scientific and technological development plan outline. The High Resolution Earth Observation System Data and Application Center (referred to as the "High Resolution Center") is a comprehensive data management platform that integrates the reception, processing, management, distribution, and sharing of high resolution data in the High Resolution Special Project. The Shandong Provincial Bureau of Geology and Mineral Resources attaches great importance to the integration and application of high score data and geological data, and vigorously promotes the integration and application of high score data and geological data.

Yi Maoqiang, Director of the Engineering Geology Department of Shandong Provincial Bureau of Geology and Mineral Resources, introduced that since July 2020, units affiliated with Shandong Provincial Bureau of Geology and Mineral Resources have been approved to build five high scoring centers. Up to now, five high tech sub centers have been listed for work, namely Weifang (the Fourth Provincial Geological and Mineral Exploration Institute), Tai'an (the Fifth Provincial Geological and Mineral Exploration Institute), Jining (Lunan Geoprofessions#Geological engineering Survey Institute), Linyi (the Seventh Provincial Geological and Mineral Exploration Institute), and Dezhou (Lubei Geoprofessions#Geological engineering Survey Institute). In addition, the Geological Surveying and Mapping Institute under the bureau has signed a data sharing agreement with the High Score Shandong Center, jointly establishing the Shandong Resources and Environment High Score Remote Sensing Application Research Institute. Through comprehensive planning and precise positioning, a high-resolution Earth observation system data and application work pattern with multi-point layout and shining stars has been gradually established throughout the province.

Highlighting Features

New breakthroughs have been made in the field of serving economic and social development

The application of high-tech research and innovation is the key.

Nansi Lake is the largest freshwater lake in northern China and an important storage reservoir for the East Route of the South to North Water Diversion Project. Its excellent water quality is of great significance. In recent years, due to the increasingly serious Eutrophication of the water body, Potamogeton crispus began to proliferate excessively in the lake area. Especially in summer, Potamogeton crispus decomposed and released nutrients, causing secondary pollution, which had a negative impact on the ecological fishery and tourism in the lake area.

We used high score data to extract the area of Potamogeton crispus in Nansi Lake in 2022, and visually displayed the growth status and coverage changes of Potamogeton crispus through remote sensing time series normalized vegetation index NDVI, which can accurately obtain the distribution information of Potamogeton crispus in Nansi Lake. "Sun Yanjian, Executive Director of High Score Jining Center, introduced that the relevant results can understand the characteristics of Potamogeton crispus and its impact on the ecosystem, Assist relevant departments in formulating governance measures to prevent their impact on the water quality of the South to North Water Diversion Project.

This is just a case of Jining Center serving regional economic and social development with high scores. In recent years, the High Score Jining Center has focused on the application of high score remote sensing technology that conforms to local characteristics, such as monitoring of coal mining subsidence areas, monitoring of surface deformation in mining areas, and monitoring of urban land subsidence. At the same time, we have also established high-tech industry innovation alliances with more than 10 enterprises and universities, accelerating the sharing and transformation of research results, and promoting the overall upgrading of the industry.

In Weifang, "cultural relics+remote sensing" opened a new track for high score Big data applications. "Give full play to the technical advantages of satellite remote sensing that can monitor in a wide range, all-weather near real-time, we have innovatively launched a high score remote sensing service cultural relics protection project, which can find early damage of cultural relics as soon as possible, and continuously track and monitor the damage of cultural relics that have been found." Fan Huifeng, president of the Fourth Academy of Shandong Provincial Bureau of Geology and Mineral Resources, introduced that since the High score Weifang Center undertook the remote sensing monitoring project of cultural relics protection units at the municipal level and above in Weifang, Provide decision-making assistance for relevant departments to prevent damage to cultural relics, and effectively prevent illegal acts of destroying cultural relics. "The main responsible comrades of the National Cutural Heritage Administration, the Provincial Department of Culture and Tourism and the Weifang Municipal Government fully affirmed our application results." Fan Huifeng is as familiar as a book.

High score Linyi Center has built a basic service system characterized by remote sensing monitoring of ecological management of mountains, rivers, forests, fields, lakes, grass and sand, built a Big data platform for geological resources and environment in Linyi, realized digital management of ecological protection and restoration, promoted the formation of a new mechanism for ecological protection and restoration, and provided accurate and comprehensive data achievements and application system solutions of mountains, forests, fields, lakes, grass and sand for government departments. Serve the "dynamic clearing" of violations of laws and regulations in the development and utilization of mineral resources in Linyi City, carry out the development and construction of dynamic monitoring methods and system platforms for mineral resources by integrating the "high score remote sensing+Internet of Things" technology, build a working mechanism of "early discovery, early stop, early investigation and early treatment", and systematically improve the comprehensive management level of mineral resources.
