摘　　要：机载LiDAR作为一种高效的空间数据采集方法得到了有效的推广和应用,利用机载LiDAR可以提取多种数据,特别是在提取DEM具有很多优势,其成果数据在城市测绘工作中可以多方面应用,如建筑物高度提取,城市整体的DEM,等高线提取等。本文以常州为例,介绍了机载LiDAR的后处理、DEM提取以及在城市测绘中的应用范例。The Airborne LIDAR as an effective spatial data acquisition method has gotten effective promotion and ap- plication. The LIDAR data can be used to extract a variety of data. In particular, it has a great advantage to extract DEM, and the results can be widely used in urban mapping work. Such as building height extraction, the whole city DEM, contour extraction. Take ChangZhou City for example, this paper introduced the postprocessing of airborne LiDAR data,DEM extraction and the application in the city Surveying and Mapping.
