Using the current domestic most new LiDAR technology to get the LiDAR data, the establishment of digital elevation model ( Digital Elevation Model, DEM). According to the requirements of the production of airport clearance protection zone reference surface. Comparison of two models of screening for ultra-high buildings. Combination of image interpretation and field have focused on the verification of measurement. Thus greatly improving the work efficiency of obstacles census. For the successful completion of airport clearance protection area obstacle survey work to provide a strong guarantee.
