三维地理信息系统矢量数据组织

Organizing of Vector Data in 3D Geographic Information Systems

摘要: 对三维地理信息系统所涉及的空间目标进行了定义,提出用三维矢量数据模型和结构来表达三维空间目标。分析了三维矢量数据结构GIS的拓扑关系。并对空间对象的数据结构进行了形式化描述。

Abstract: The 3D spatial objects related to 3D geographic information systems are defined, and 3D vector data model and structure are put forward to represent the 3D spatial objects. Meanwhile, the topologic relations of the 3D data structures are analyzed and the data structures of the spatial objects are formally described.
