基于空间离散网格模型的月表信息表达

由于平面数据模型在月球全球空间信息管理方面的局限,利用空间离散网格数据模型来构建具有连续性、层次性以及动态的月球空间信息管理系统成为解决问题的有效手段之一。本文通过对空间离散网格的研究,基于二十面体采用空隙度为4的递归剖分,并采用了在空间仿真方面应用广泛的六边形作为网格的基本单元,建立六面体全月球的空间离散网格模型,并对其特性进行了分析,利用该模型对月球虹湾地区地形进行表达。

Expression Of Lunar information Base On Spatial Discrete Grid

With the development of the exploration of the lunar in technology,On the ongoing the aircraft has been launched,which carries scientific instruments will gain an increasing number of information on the moon,the storage 、the expression and the use of the volume data will be a problem of the global scientific research to the Moon.For the limited of the plane model data on the moon Global Space Information Management,the use of space separated grid data models to build a continuous one,as well as developments in the level of the moon Spatial Information Management System has become an effective means of solving the problem.of By the study on the Space separated grid through this network,based on the physical gap at 20 degrees in the part for the delivery,and the use of space simulation of the extensive application of grid 6 side as the base,building the Space separated grid model of six sports moon body,Then analysis of their properties.
