Tree species classification based on full-waveform airborne laser scanning data

Airborne laser scanning is an evolving operational measurement technique for deriving forest parameters. The objective of the current study was to analyze the potential of full-waveform airborne laser scanning for tree species classification of a mixed woodland. The quantities used were the echo width, backscatter cross section, as well as the distribution of the echoes in vertical direction. Based on segmented tree crowns the mean backscatter cross section of all echoes above the 50th height percentile was computed. Additionally, the canopy density, describing the ratio of the number of all echoes above the 50th height percentile and the total number of echoes, was used for a knowledge-based classification of…
