Lidar has provided one new method for the digital elevation model (DEM). It has the advantage of gaining the three dimensional information, the wide measuring range, the high spatial and elevation resolution. What the lidar system gains is the cloud data, which can produce the digital surface model of the scanning area directly. However, if we want to… CONTINUE READING
