摘　　要：以厦门市城市三维建模为例,介绍了基于VrMap与Sketch up的三维建模技术路线,同时就三维符号库的建立,数字地面模型制作,三维建筑建模、优化、纹理映射、以及属性添加等一系列问题进行了详细的探讨和阐述.This paper proposes a new approach for urban 3D modeling based on VrMap and Sketch up, and presents some examples of 3D modeling in Xiamen, China. At the mean time, this paper also discusses some key points in detail, such as the constructing of 3D symbolbank, the digital ground model, 3 D architecture model, model optimization, texture mapping and attribution appending.
