Interpretation of upper-storey canopy area in subtropical broadleaved forests in Okinawa Island using laser scanning data

Conventional forest inventory practice took huge of effort, and is time- and cost- consuming. With the aid of remote sensing technology by light detection and ranging (LiDAR), those unbearable factors could be minimized. LiDAR is able to capture forest characteristic information and is well known fo...
