摘要
数字城市是城市信息化的重要组成部分,随着信息技术的发展,对数字城市三维模型提出了更高的要求,而现有的三维建模手段不能满足这种需求。BIM技术的发展为数字城市三维模型建立提供了更精确的手段。文章通过分析BIM与GIS区别,从数据组织、应用模型等方面探讨BIM技术在数字城市三维建模中的应用。
The Digital City Construction is an important part of the city information construction. With the de- velopment of information technology, on the three-dimension models of digital city put forward higher requirements, higher requirements of 3D Digital City have been proposed. However, the existing 3D modeling tools could not meet this demand. Fortunately, the development of BIM has provided a more accurate measure for 3D model of the Digit- al City. By analyzing the difference between BIM and GIS, The article discusses the application of BIM technology in the 3D modeling of the Digital City in terms of data organization and application.
