随着LiDAR技术的普遍应用,高精度DEM数据和高分辨率DOM数据在道路设计中的应用越来越广泛。目前,大部分的设计单位仅将DEM数据和DOM数据应用于地形图调绘、横断面信息获取等方面。着重讨论的是如何将DEM数据和DOM数据与道路设计方案结合到一起,使道路设计方案直观、真实、精确与实地相结合,且可以利用DEM数据和DOM数据进行项目地形分析和设计方案浏览、地质解译分析、设计方案汇报等工作。
With the widespread application of LiDAR technology, the application of high-precision DEM data and high-resolution DOM data in road design is more and more widely used. At present, most of the design units only apply DEM data and DOM data to topographic drawing and cross-sectional information acquisition. It focuses on how to combine DEM data and DOM data with the road design scheme to make the road design scheme intuitive, true and accurate combined with the field. The DEM data and the DOM data can be used to browse the project topographic analysis and design scheme, Geological interpretation analysis, design reports and other work.
