基于GIS的泉州历史古城三维可视化与应用

3D visualization and application of Quanzhou historical city based on GIS

对比各种GIS三维可视化方法,利用Arc GIS和Sketch Up等软件设计泉州市历史古城三维建模技术路线,构建地面模型、建筑主体以及周边植被环境等附属物的三维模型,并在Arc Scene场景中实现三维可视化,依据三维模型可用于历史古城规划等应用。结果表明,利用GIS三维建模可以为古城保护开发工作提供科学的决策依据。

After comparing different kinds of GIS visualization and using Arc GIS and Sketch Up software,the model of the main body of the ancient building on the ground,and the surrounding vegetation and environment of the historical ancient city of Quanzhou were constructed,with visualization of 3D scene in the Arc Scene. The 3D model can be used for applications such as the historical city planning. The results show that using GIS three-dimensional modeling can provide scientific decision for the protection and development of the ancient city.
