Based on GeoSOT-3D, a non-overlapping, orthogonal, latitude-longitude consistent grid in the spheroidal space, a true 3D representation method is proposed. The method includes two steps: subdivision preprocessing and subdivision expressing. The experimental result, obtained from using atmospheric data, verifies the feasibility of the method, and it provides a new idea for the representation of global observation data.

Key words: true 3D representation, three-dimensional spatial data, three-dimensional subdivision grid, GeoSOT-3D


基于面向地球空间, 且具有边界不重叠、网格正交、经纬一致、与传统数据规格兼容性好等特点的GeoSOT-3D立体网格, 提出一种三维数据表达方法。该方法设计剖分预处理和剖分表达两个步骤来完成空间数据的真三维表达, 并对大气观测数据进行三维展示实验。实验结果验证了该方法的可行性, 为全球空间数据的表达提供一种新的解决思路。
