摘要
基于SketchUp 6.0,ArcGIS软件平台,研究了地下空间信息3维可视化的实现过程,强调利用ArcEngine接口功能函数、3维几何对象Multipatch实现某些规则地下空间信息的参数化3维建模。对于AutoCAD数据,采取数据格式转换与ArcEngine编程两种方式实现数据3维可视化及入库。另外,从空间信息管理系统的角度,阐述了地下空间信息系统的结构、数据库组织管理及功能实现,并结合相关应用给予说明。
Based on the SketehUp6.0 and tkrcGIS software platform, this paper studies the process of 3 -dimensional visualization of underground space information focusing on 21 - dimentional parametric modeling of some regular underground spatial information using ArcEngine interface function and 3 - dimensional geometric object Multipatch ,visualizes and stores data 3 - dimentioanally through data format conversion and ArcEngine programming for AutoCAD data, elaborates the structure and database management and organization function of underground spatial information system from the point of view of spatial information management system based on the demonstration of related applications.
