摘要
高精度道路DEM在城市内涝的防控与治理中具有重要的作用。针对传统DEM制作数据采集与处理烦琐,生产周期长等问题,本文利用新型基础测绘技术,以城市行洪道路为研究对象,提出利用移动测量技术制作高精度道路DEM的方法,提高了DEM的生产效率和数据精度,并将DEM成果应用到城市内涝防治和治理工作中,取得了很好的效果。
High precision road DEM plays an important role in the prevention and control of urban waterlogging.In order to issues such as cockamamie data collection and processing,and long production period in traditional DEM production,This article uses new surveying and mapping technology,taking urban waterlogged roads as the research object,and proposes a method of using mobile measurement technology to produce high-precision road DEM,this method improves the production efficiency and data accuracy of DEM,and applies the results of DEM to urban waterlogging prevention and control work,achieving good results.
