【摘要】 地学三维矢量数据生成长期以来一直是三维GIS研究中的一个难点,该文将传统二维GIS的拓扑关系引入到剖面数据中,提出了一种基于剖面拓扑关系的三维空间实体自动生成的算法,并提出了在该方法下断层问题的解决方案。更多还原

【Abstract】 D vector data creation is a difficult problem in three-dimensional GIS research.This thesis imports the traditional topological relationship of2D GIS into section data and puts forward an automatic3D vector data creation algorithm based on topology of section data.Furthermore,it also suggests a method to solve the fault relative problems.更多还原
