Abstract：With the development of surveying and mapping technology， airborne LiDAR technology has been widely applied. This article uses point cloud data of airborne LiDAR to study the production methods of geomorphic elements in 1∶10000 topographic maps. Through production experiments and accuracy testing in the research area， the results show that the product accuracy meets the production requirements of geomorphic elements in 1∶10000 topographic maps and meets the relevant elevation accuracy requirements.
