GROUND SURFACE VISUALIZATION USING RED RELIEF IMAGE MAP FOR A VARIETY OF MAP SCALES
Ground surface RRIM Visualization
2016/7/8
There are many methods to express topographical features of ground surface. In which, contour map has been the traditional method and along with development of digital data, surface model such as shad...
Usually, filtering is performed in order to extract a ground surface from laser points obtained with the airborne laser scanner. It
mainly removes the laser points that were measured as trees surfac...
