| 摘 要：为解决城市轨道交通工程各专业之间协调合作困难问题，并进一步提升城市轨道交通监测管理能力与可视化展示效果，本文以三维地形数据的获取与发布、海量GIS数据的显示策略、BIM模型数据的处理与加载为出发点，提出一套实现BIM-GIS数据融合与地理位置配准的解决方案，并通过合肥市轨道工程进行验证。在此基础上利用Cesium开源地图引擎，开发以BIM与GIS多源数据集成应用为核心的Web管理平台，该平台以WebGL为容器，Web服务为链接，实现大范围真实地理空间环境下BIM模型的地理配准与数据的对象级管理，同时实现了城市轨道交通实时监测与安全预警可视化展示，为城市轨道交通三维场景构建与数字化交付应用提供了技术支持。 |

| Abstract:In order to solve the difficult problem of coordination and cooperation among various majors in urban rail transit engineering, and to further improve the monitoring and analysis ability as well as visual display effect in this area. This article set the acquisition as well as release of 3D terrain data, display strategy of massive GIS data and the processing as well as loading of BIM data as the starting point, put forward a set of BIM and GIS data fusion and coordinate system transformation to achieve location registration solution, which is implemented in Hefei Railway Project. On this basis this article applies Cesium open source map engine to develop a Web management platform based on the integrated application of BIM（Building Information Model）and GIS（Geographic Information System）multi-source data as the core.This platform takes WebGL as the framework and Web service as the link to realize geographic registration of BIM model and the object level management of BIM data in a large range of real geospatial environment. Meanwhile, it offers a visual platform for real-time monitoring and security warning of urban rail transit. It also provides a reference for the construction of 3D scene and digital transfer application of urban rail transit. |
