Abstract

Abstract: This paper introduces the general technical route based on the airborne LiDAR point cloud data acquisition and high-precision DEM construction in Guangdong Province.For solving the difficulties,the paper researched some key technologies and solutions from five aspects:equipment selection,point cloud density design,data obtained method in mountainous areas covered densely,point cloud data classification and combination algorithm,and blank area processing.Research of this paper will be beneficial for the design and implementation of similar projects.

Key words: airborne LiDAR, DEM, point cloud density, data acquisition, point cloud data classification
