摘要
分析了已有全球及中国岩石圈板块模型、厚度、地形数据多源异构的现状,并研究球体退化八叉树格网全球尺度连续、多层次、网格变形小、可动态编码的特点。首先针对收集到的岩石圈板块数据多源异构的特点,对原数据进行预处理,然后基于球体退化八叉树格网建模与可视化的要求,对预处理后的岩石圈数据进行组织,并采用该数据组织方法对处理数据进行实验,实验结果表明采用该数据组织方法,可以较好地为岩石圈板块的三维建模与可视化提供技术支持。
This paper analyzes the existing global and China lithosphere plate model,thickness,terrain multi-source heterogeneous data of present situation,and researches on Sphere Degenerated Octree Grid（SDOG）,which is based on the geocentric coordinate system and sphere degenerated octree.SDOG is of features of multi-hierarchy,multi-resolution,and distortion stability both in grid area and grid volume,dynamic coding.Firstly the lithosphere plate to collect the characteristics of multi-source data of the heterogeneous data pretreatment,based on Sphere Degenerated Octree Grid modeling and visualization,at the request of the lithosphere data after pretreatment by this organization,and data organization to handle data experiment method,experimental results shows that the data organization methods can be good for the lithospheric plates and visualization of three-dimensional modeling to provide technical support.
