摘　　要：建筑信息模型(BIM)主要应用于单体建筑,所构建的模型可以反映建筑物各部件细节。地理信息系统(GIS)具有强大的数据处理和分析功能,广泛应用于市政规划、智慧水利、智慧交通、应急安保、智慧城市、三维房产等领域。而传统的GIS技术仅适用于宏观模型的展示,只能反映建筑物的外观和地理位置,无法获取建筑物内部细节,其与BIM的相似之处在于,它们都是空间信息的模型,前者主要用于室外建模,后者侧重于室内建模。本文主要研究利用GIS+BIM技术对建筑物计算机辅助设计(CAD)数据进行数据转化、分析处理以及三维建模,最后实现BIM模型可视化。此方法使GIS的应用由室外走向室内,从宏观世界走向微观建筑,完成了部件级三维模型的建立,对探索GIS+BIM的三维建模研究具有一定的现实意义和应用价值。Building information modelling(BIM)is mainly applied to single buildings,and the model constructed can only reflect the details of each component of the building.Geographic information system(GIS)has powerful data processing and analysis functions,and it is widely used in municipal planning,intelligent water conservancy,intelligent transportation,emergency security,smart city,three-dimensional(3D)real estate,and other fields.However,traditional GIS technology is only applicable to the display of macro models and can only reflect the appearance and geographical location of buildings,failing to obtain the internal details of the buildings.Similar to BIM,they are both spatial information models.GIS is mainly used for outdoor modelling,while BIM focuses on indoor modelling.This paper mainly studied the application of GIS+BIM technology to transformation,analysis,and processing of buildings’computer aided design(CAD)data and 3D modelling and finally realized the model visualization of BIM.This method extended GIS from outdoor application to indoor application and from the macroscopic world to the microscopic architecture,and it completed the establishment of a component-level 3D model,which had certain practical significance and application value for exploring the 3D modelling research of GIS+BIM.
