| Abstract: | DEM and DOM have become important productions of aerial remote sensing, the point cloud data with three-dimensional coordinate information acquired by airborne LiDAR system can produce DEM and DOM without ground control points after system error correction and filtering, and combined with POS data and digital images.The practice shows that results meet the precision of 1∶2 000 scale DEM and 1∶5 000 scale DOM accuracy specification, the method has a short production cycle and high quality outcome, can sat-isfy the need of mapping in no men land and emergency situations. |
