基于机载激光扫描技术的1∶1000地形图制作

1∶1000 Topographic Map Production Based on Airborne Laser Scanning Technology

机载激光扫描技术的出现使得大比例尺地形图的制作有了更加便捷的数据来源,本文通过实际测区进行试验,全面介绍了基于机载激光扫描技术的1∶1000地形图制作所有过程,包括点云数据采集、矢量提取以及编辑等,完成了整个测区的1∶1000地形图制作。最后使用全站仪采集检验点对本文方法完成的大比例尺地形图成果进行精度检验,验证了使用机载激光扫描技术进行大比例尺地形图制作的可行性。

The emergence of airborne laser scanning technology has provided a more convenient data source for the production of large-scale topographic maps,this paper conducts an experiment in a real survey area and comprehensively introduces the entire processes of producing 1∶1000 topographic maps based on airborne laser scanning technology,including point cloud data acquisition,vector extraction and editing,etc.The production of 1∶1000 topographic maps for the entire survey area is completed.Finally,a total station is used to collect checkpoints to verify the accuracy of the large-scale topographic maps produced by this method,thus verifying the feasibility of using airborne laser scanning technology for the production of large-scale topographic maps.
