Remotely sensed data are widely being used for the identification and extraction of vegetation from land surface observations. Conventional sensors have limitations in fully representing the three-dimensional structure of vegetation, which can be overcome by laser scanning (LiDAR). Most of the research on vegetation studies using lidar has been in forestry. Very few studies have looked at mapping vegetation, including low vegetation, for topographical mapping from lidar data. The aim of this study was to evaluate the classification and extraction of vegetation for topographic mapping using full-waveform airborne laser scanning data from the Avonmouth area of Bristol. The laser data was captured at a height of approximately 950m above ground level providing a point density ranging from 0.5-0.8 per m2.
