It seems that the promise of full waveform technology has not yet been realized. This team of researchers at the University of Heidelberg in Germany note that for the forestry application at least “an extensive overview, categorization and comparison of features from full-waveform airborne laser scanning and how they relate to specific tree species are still missing.”
To address this they provide a review that “identifies frequently used full-waveform airborne laser scanning-based point cloud and waveform features for tree species classification and compare the applied features and their characteristics for specific tree species detection. Limiting and influencing factors on feature characteristics and tree classification are discussed with respect to vegetation structure, data acquisition and processing.”
