摘　　要：三维地理信息建模是测绘地理信息行业近年来发展的新技术,其建立的三维城市模型已经是数字城市、智慧城市地理空间框架数据的核心内容之一。本文主要介绍了三维地理信息建模的3种典型建模方法及其建模步骤,并以具体图片展示其建模结果,最后结合3种方法的各自特点分析了其优缺点及其适合的建模应用领域。3D geographic information modeling is a new technology developed in recent years in surveying and mapping geographic information industry. The 3 D urban model has been one of the core contents of geo-spatial frame data of digital city and intelligent city.This paper mainly introduces three typical modeling methods and modeling steps of 3D geographic information modeling,and presents the modeling results with concrete pictures. Finally,combined with the characteristics of various methods,it analyzes their advantages and disadvantages and suitable modeling application fields.
