Multi-source heterogeneous lithospheric plate data processing and visualization

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.
