| Abstract: | The hardware of airborne LiDAR technology has been relatively mature in foreign countries,but the data post-processing and applications of LiDAR data are still on research and development stage.In this paper,basing on the comprehensive study of LiDAR data filtering methods and the various characteristics of a multiple echo,a method to extract the information of trees was developed and carried out.Compared with traditional visual interpretation method,the method's feasibility was verified and also it could p... |
