地月一体圈层立体网格数据组织模型研究

The research scope of earth science has expanded from its origin planet to the entire Earth-Moon space and even greater range increasingly. But existing Geoscience data organization models are based on the earth itself, it is hardly to meet the three-dimensional distribution, across temporal and spatial scales, seamless connection needs of the spatial information in the Space Science..The Earth-Moon integration sphere shell 3D grid is proposed, which is the inheritance and development of sphere shell structure grid theory. This new kind 3D grid which seamlessly covers the entire Earth, Moon and the Earth-Moon space environment is established. The space subdivision and coding algorithm of both Earth and Moon sphere shell 3D grid are consistent, multi-source data integration, the SFC based index method have been investigated in, and the prototype system is built up, and then the construction techniques of ocean, underground, atmosphere, space construction based on the sphere shell solid grid model. The transformation relationship of the grid cell code between Earth Grid and Moon Grid are setup. And multi-source , massive Earth-Moon space environment data organization and management techniques are presented. At last, the prototype is built for spacecraft simulation and security management which is chosen as the application test..This project can be used as the unified description of the Earth-Moon space exploration activities and the integration of multi-source massive spatial information. It provides one kind of foundation platform for frontier research field of earth system science, and promote the further development of 3D space grid research.

当前地球科学的研究范畴日益走出其发源的地球环境，已经将整个地月空间乃至更大范围作为研究对象。但是，现有地学数据组织模型都是以地球为研究对象，难以满足地月空间科学研究中空间信息立体分布、跨空间层次、跨时空尺度、无缝隙衔接的需求。.本项目继承和发展“圈层化”的网格构建思想，提出地月一体圈层立体网格模型，拟实现无缝涵盖整个地球、月球、地月空间环境的新的立体空间网格，设计地月统一的网格剖分编码算法，构建地球圈层立体网格、月球圈层立体网格，建立地—月圈层立体网格之间网格单元的编码变换关系，研究海量、多源地月空间环境数据组织管理技术，结合空间飞行器仿真与安全管理开展应用试验。.本项目可用于地月空间探测活动的统一描述和多源空间信息的集成组织，为地球系统科学前沿研究领域进行多学科交叉集成研究提供一个基础平台，推动立体空间网格研究领域的深入发展。
