| Abstract: | LiDAR technology is developing very fast in recent years,applicable potential is huge.This paper introduces LiDAR data classification in TerraSolid briefly,then emphasizes on the discussion of DEM and vector automatic extraction from LiDAR data.The accuracy of DEM extracted from LiDAR is high,but the vector automatic extraction does not reach practical stage. |
