摘要
由于沙漠地段气候恶劣,常规的勘测手段既费时又费力,利用数字化手段既能实现沙漠数据信息的精确采集,还能提高工作效率。本文以沙漠公路为依托,基于多源数据融合技术建立了完整的沙漠公路BIM模型,并对沙漠公路数据来源、数据采集方式进行了研究。通过对该模型在GIS场景里的多尺度应用分析,建立了一套多时空维度的空间数据库,实现了海量数据集成化管理,拓展了三维数据在建设项目中的应用渠道,可为沙漠公路数字化信息管理平台的建立提供基础保障。
Due to the harsh climate in desert areas,conventional survey means are time-consuming and labor-intensive,while digital means can not only obtain accurate data and information,but also enhance work efficiency.In this thesis,a complete BIM model of desert highway is proposed based on multi-source data fusion technology,and the data sources and data collection methods are studied.Through analyzing the multi-scale application of the proposed model in GIS scenarios,a set of spatial databases with multi-temporal and multi-spatial dimensions are established,which realizes the integrated management of massive data and expands the application fields of 3D data in project construction,and moreover,provide support for the establishment of digital information management platform of desert highway.
