摘要
利用目前国内最新的LiDAR技术获得的LiDAR数据,建立数字高程模型(Digital Elevation Model,DEM)。根据机场净空保护区要求制作参考面,对比两个模型后筛选出超高建筑物。结合影像判读后再进行外业有重点的核查测量,从而提高了障碍物普查的工作效率,为顺利完成机场净空保护区障碍物调查工作提供了有力的保障。
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.
