| Abstract: | DEM extraction is one of the important uses of LiDAR data acquisition. However,due to the limitations of the current algorithm,it cannot be classified automatically with high precision. How to re-classify the algorithm after classification based on certain principles and standards to get a more accurate DEM is still a major problem in the field of expertise. In this paper,a. LAS data reextraction,greatly improving the accuracy of its DEM for the future of some units and individuals using TerrSolid software on the airborne radar DEM re-extraction to provide some experience. |
