At present, the technology of generating high precision and high current digital elevation model (DEM) based on airborne light detection and ranging (LiDAR) data has been widely used. It is urgent to control the quality of DEM data scientifically and efficiently. In this paper, the authors introduce the three-step inspection method based on practical production experience, which includes human-machine interpretation discriminant inspection, semi-automatic inspection and automatic inspection through python. This method comprehensively covers the quality inspection of DEM generated by airborne LiDAR technology and provides the solution, thus improving the efficiency and accuracy of quality inspection and filling the blank of nonexistence of ready-made software and methods for completing the work.
