基于Sketchup利用大比例尺地形图制作城市三维建筑模型的方法

Method of Producing 3D City Building Model By Using Large Scale Topographic Map Based on Sketchup

目前,三维模型数据快速生产是三维GIS建设面临的主要问题。而Sketchup作为一款方便易用的三维建模软,在构建大区域三维建模工程时,能够有效提高建模速度和建模质量,避免同类设计制作软件的复杂性,提高建模工作效率。本文通过实例,探讨了基于Sketchup利用大比例尺地形图制作三维建筑模型的技术方法和流程,为从事三维GIS模型数据生产者提供些许参考。

Currently,fast production for data of the three-dimensional model is a major problem faced by the con- struction of three-dimensional GIS. In building a large 3D modeling project, Sketchup as a convenient and easy-to-use 3 D modeling software can effectively improve the modeling speed amd modeling quality, to avoid the complexity of similar design software. By instance ,this article explores the technical methods and procedures of producing three-dimensional building model based on Sketchup software and large-scale topographic map, in order to provide a little reference to workers who have been engaged in production of three-dimensional GIS model data.
