摘要
在三维GIS平台中构建地形模型、道路模型、建筑物模型等,采用三维数字方法呈现客观世界环境,需要集成处理模型,使模型要素形成模型系统。文中针对建筑物、道路等地物模型与地形模型的连接匹配方法进行研究,分析三维GIS特点与地物要素应用重点,分析匹配地物与地形模型的主要方法。
In 3D GIS platform,terrain models,road models,building models and so on are constructed.3D digital method is used to present the objective world environment.The integrated processing model is needed to make the model elements form a model system.This paper studies the connection and matching methods between building,road and other ground feature models and terrain models,analyzes the characteristics of 3D GIS and the application focus of ground feature elements,and analyzes the main methods of matching ground feature and terrain models.
