LiDAR数据获取快、精度高,具有传统摄影测量方法和常规测量技术无法比拟的优越性,为等高线的获取提供了新的思路,在测绘行业越来越受到关注.本文通过生产实践,解决了平原地区生成等高线的瓶颈,提出了一个基于机载LiDAR数据制作等高线的标准化流程,并重点介绍了相关的细节处理.
The LiDAR data, which get fast and with high precision, has more superiority than the data getting by traditional photogram-metry method and conventional measurement technology, provides a new method for contour generation, causes more attention in the surveying and mapping field. Through practice in the production, this paper solves the bottleneck problem of contour generation in plain area, and puts forward a standardized process of making contour lines based on airborne LiDAR data.
