Construction and Analysis of Three-dimensional Model Based on BIM and GIS Technology
The purpose of this study is to explore the potential of the combination of building informa-tion model(BIM)and geographic information system(GIS)in solving problems in the construction in-dustry.By using Revit software to build BIM model and importing it into geographic information software,3D model analysis is carried out to explore the value of more 3D data.The research results show that the combination of BIM-GIS provides great potential for solving the problems of the construction industry.By integrating BIM models and geographic information,comprehensive and accurate building models can be obtained,including geometric attributes,component information,time schedule and cost data.Through the analysis of three-dimensional models,we can better understand the relationship and influence of build-ings in geospatial space.In the stage of building operation and maintenance,we can monitor and predict the state of buildings in real time and provide effective decision support,which brings more opportunities and development space for the construction industry.
