摘要
实时的3维GIS系统突破了传统的2维GIS软件在实时性、表现手段、仿真分析功能等方面存在无法克服的局限性,提供了强大的实时3维地理数据管理分析、可视化和科学计算功能,支持空间信息查询和属性数据库查询和管理。本文以山西省为例讨论了建立3维地理信息平台的方法和步骤,并提出了一些关键技术的解决方案。
The real-time 3 D GIS overcame the limitations of traditional 2D GIS in real-time, expressive methods, emulational analysis functions and other aspects. It presents powerful real-time management and analysis of 3D geographical data, visualization and scientific computation functions. It also supports the query and management for spatial and attribute information. This paper discussed the methods and steps to construct 3D geographic information platform and put forward some solutions of key techniques.
