| Abstract: | LIDAR or Airborne Laser Scanning as a powerful remote sensing technology for survey in different areas, suchar urban forest coastal areas,for instance,has received increasingly intensive attention in the last several years.The paper describes the characteristics of LIDAR data, irregular 3D points cloud, and its advantages and disadvantages. In addition,some issues about LIDAR system and some problems related with such data are also discussed briefly in the paper,which facilitate the understanding of LIDAR data characteristics. |
