| Abstract: | Based on WebGIS technology, this paper studied the construction method of railway line 3D scene and applied it to engineering practice. The paper used Digital Elevation Model (DEM) and high-resolution remote sensing images to construct the 3D banded geographical environment of railway line, carried out the parametric modeling of railway engineering element model, and implemented the interactive positioning between Building Information Modeling (BIM) and 3D geographic environment scene. Based on ArcGIS online platform, the paper realized the application of 3D scene publishing, online browsing, spatial analysis and other functions of a certain railway line. |
