GIS三维可视化在数字文化遗产中的应用

Application of 3DGIS in digital cultural heritage

通过对数字文化遗产的分析,本文运用三维可视化技术,提出基于微机平台建立文化遗产GIS三维可视化系统的设计方案;并通过一个典型仿唐木构建筑群的虚拟展示为例,介绍了实用的多种类型数据库管理及基于数据库的实时应用方法,包括若干关键技术:LOD数据集成、多模态可视化、室内外三维一体化显示与漫游和多媒体属性查询。通过此应用实例,证明该方案投资少,开发方便,具有一定现实意义。

A Three Dimension Geographic Information System (3DGIS) for the digital documentation of a special T'angwooden buildings based on personal computer is introduced in this paper. The practical methods of LOD models' data integrated management and database based on realtime visualization are presented in detail.
