摘　　要：智慧城市建设与管理需要宏观空间数据与微观空间数据的结合,而现有空间数据可视化方法由于渲染顺畅度不够,存在着帧率过低的缺陷,无法满足现今智慧城市建设的需求,故提出基于GIS+BIM的空间数据可视化方法研究。制定GIS+BIM混合模型可视化渲染规则,为空间数据可视化做准备,以此为基础,利用ArcGIS软件获取GIS矢量白模,采用轮廓检测算法提取BIM模型外轮廓,以获取的GIS矢量白模与BIM模型外轮廓为基础,构造三维瓦片数据,将其作为空间数据可视化集成容器,并对多层瓦片进行组织,从而实现了空间数据的可视化。实验结果显示:在不同实验次数内,不同LOD层级条件下,提出方法的空间数据可视化帧率远远高于现有方法,充分证实了提出方法具备更好的应用性能,能够更好地为用户服务,适合对其大力推广与应用。The construction and management of smart city need the combination of macro spatial data and micro spatial data.However,the existing spatial data visualization methods cannot meet the needs of today’s smart city construction due to the lack of smooth rendering and low frame rate.Therefore,a spatial data visualization method is proposed based on GIS + BIM.The visualization rendering rules of GIS + BIM hybrid model are formulated to prepare for spatial data visualization.On this basis,the white model of GIS vector is obtained by ArcGIS software,and the outer contour of BIM model is extracted by contour detection algorithm.Based on the obtained white model of GIS vector and the outer contour of BIM model,the 3 D tile data is constructed,which is used as the integration container of spatial data visualization,and the multi-layer tiles are analyzed So the visualization of spatial data is realized.The experimental results show that: in different experimental times and LOD levels,the frame rate of spatial data visualization of the proposed method is much higher than that of the existing methods,which fully proves that the proposed method has better application performance,can better serve users,and is suitable for its promotion and application.
