Research on Construction of 3D GIS Scene of Railway Bridge BIM Based on Cesium
With the continuous advancement of digitization,informatization and intellectualization in the field of railway engineering,it has become a development trend to integrate the railway engineering information model with a large-scale real geographical environ-ment,and display 3D scene of railway engineering through online visualization an distribution sharing.From the construction of rail-way 3D geographic scene,railway bridge BIM parametric modeling,fusion and positioning,to the development of 3D scene interaction and application function,this paper designs an overall scheme based on open source Cesium platform and realizes 3D roaming,spatial query,terrain analysis,sunshine analysis,profile analysis and other functions for railway engineering bridge information model.It provides a technical path for the open and shared management and demonstration of BIM+GIS in railway digital engineering applica-tion.
