实景三维助力国际海底地理实体命名
Core Insights - The Ministry of Natural Resources and the National Bureau of Statistics jointly released a list of exemplary cases for high-quality development innovation applications empowered by real-scene 3D technology, with the "Real-Scene 3D Empowerment of International Seabed Geographic Entity Naming" case recommended by the National Marine Information Center being included [1][2]. Group 1: Technological Applications - The application of real-scene 3D technology allows for the visualization of seabed geographic entities such as seamounts, ridges, and canyons, enhancing the scientific accuracy of identifying these entities [1]. - A rapid extraction and classification method for seabed geographic entities has been developed, enabling automated identification and scientific calculation of key parameters like shape, scale, and slope [2]. Group 2: Management and Standardization - A semantic attribute collection for seabed geographic entities has been established, creating a coding system that integrates individual entities with their groups, facilitating a smart management model [2]. - The case has led to the standardization of seabed geographic name proposals, improving the acceptance rate of these proposals in international reviews, particularly in disputed maritime areas [2][3]. Group 3: Institutional Role - The National Marine Information Center has been responsible for leading domestic seabed name proposal compilation and technical review since 2010, having submitted 283 seabed name proposals to the international seabed name registry [3]. - Future applications of real-scene 3D technology will focus on constructing a comprehensive marine scene, enhancing the effectiveness of marine spatial geographic data in supporting high-quality marine economic development [3].
