This article introduces a road model drawing method based on Cesium,and provides a detailed introduction of using Cesium's API and JavaScript programming implementation with a railway engineering example.This method can quickly generate a road model based on road route and section parameters,vividly and intuitively display basic road information and features.Combined with three-dimensional map terrain and landform information,it realizes three-dimensional visualization drawing and interaction,providing effective decision-making basis for the comparison and selection of road construction planning schemes.
