摘　　要：城市地理标记语言(CityGML)是一种用于3D城市和景观模型的建模和交换的建模语言,用于描述3D城市对象的通用信息模型。传统城市建筑模型数据获取手段多,处理工作量庞大,大量模型为整体表达建筑外轮廓模型,没有区分建筑物的不同结构和属性,不利于后续模块化分析应用。针对这一问题,本文探索基于CityGML 3.0标准对城市大规模建筑物进行建模的方法,按数据准备、模型构建、编辑检查及纹理贴图等步骤进行分析,并对所建模型成果进行验证。本方法可为城市三维模型建设、管理及使用提供借鉴。City Geographic Markup Language(CityGML)is a language for generating and exchanging 3D city and landscape models,as well as a general information model for describing 3D city objects.The traditional city building model data acquisition means are many,and the processing workload is huge.A large number of models are the overall expression of the building contour model,which does not distinguish the different structures and properties of the building,and therefore it is not conducive to the subsequent modular analysis and application.To solve the problem,this paper explores the method of modeling large scale city building based on the CityGML 3.0 standard,and analyzes and verifies the process by data preparation,model construction,editing and checking,texture mapping and other steps.The method can provide reference for the construction,management and application of 3D city model.
