| 摘 要： | 选定月固坐标系为月球圈层空间网格的坐标基础,根据月球结构及其人造月球卫星轨道分布情况划分月球基准圈层面,采用剖分曲线l和b对月球圈层面进行层次细分,实现对圈层面层次细分。然后,结合圈层径等距细分对月球圈层体进行层次细分,实现对圈层体层次细分,建立月球圈层空间立体网格模型。采用Hilbert曲线填充算法,实现对月球圈层网格统一编码,编码效率较高,为网格数据组织奠定基础。

| Abstract: | Lunar￣fixed coordinate system was selectecl as the basis of Lunar shell space solid grid. According to the structure of Lunar and the distribution of the man￣made lunar satellite the lunar base shell surface was determined and was subdivided into small parts by partition curve l and b. Then complying with the equidistant subdivision on the shell radial direction shell volume was subvided into small parts and the model of Lunar shell space solid grid was established. The effective encoding method to lunar shell grid was realized by Hilbert space￣filling curve which established the foundation to grid data organization. |
