LiDAR-DP在广西多植被及陡石山DEM生产中的应用

Application of LiDAR-DP in Multi-vegetation and Craggedness Mountain DEM Production in Guangxi

广西地区植被茂密且有大量岩溶地形,地貌具有一定的特殊性。在应用机载LiDAR进行DEM生产时,工艺与常规地貌略有不同。讨论了国产机载LiDAR数据处理软件LiDAR-DP的功能特点和生产流程,并将其应用到实际DEM生产中进行实验,总结了该软件的使用方法。实验表明,LiDAR-DP自动化程度高并且操作简捷,独特的分类工具可以大幅提高作业效率。

Guangxi Zhuang Autonomous Region has thick vegetation and a large number of Karst topography.The landforms are very special and representative.When using airborne LiDAR to produce DEM,the process used for this topography is slightly different from conventional landforms.In this paper,we discussed the functional characteristics and production flow of LiDAR-DP,which was domestic airborne LiDAR data processing software.And then,we applied LiDAR-DP to actual DEM production and summarized the use of this software.The experimental results show that LiDAR-DP has a high degree of automation and is simple to operate.The unique classification tool can greatly improve the operating efficiency.
